How do I install Allway Sync?

Download the distribution file from the download page. You can safely ignore Internet Explorer security warnings about the dangers of downloading executable files - this software does not contain any viruses, spyware, adware, or any other malicious software. See the end user license agreement for details. When the download window appears, click the "Open" or "Open this program from its current location" choice. If you do select "Save", please make note of the directory into which the program is saved and execute the installation program from saved location. Follow the installation instructions. By default, the application is installed in the "Program Files" folder on the system drive.

How do I uninstall Allway Sync?

Be sure to close all running instances of Allway Sync. If you use a multi-user configuration of Windows, you have to exit running instances (of Allway Sync) running in other (inactive) user accounts also. Select Control panel/Programs and Features in the Start menu. Locate Allway Sync and follow the uninstaller instructions.

Do I need to uninstall the old version before installing a new one?

Only if you want to install in a different folder. Unless otherwise noted, the new version retains options and settings from the previous one.

How can I use Allway Sync for data backup?

Refer to our Data Backup with Allway Sync article.

How does Allway Sync determine if a file is changed?

See Synchronization Algorithm Description.

I have a big number of files to sync. Does the synchronizer have any limitations on the number of synced files?

The sync algorithm has no limitations on the number of synced files, but Windows has restrictions on the amount of the operative memory that can be used by an application at once. For this reason, there are limitations to the number of files that can be synced.

64-bit Windows editions can use more memory than 32-bit editions. So, if you have a lot of files that should be synced at once, there is reason to use the 64-bit edition of the synchronizer.

What happens if a network connection drops during synchronization?

No files will be lost. When Allway Sync replaces a file, it first copies it to a temporary file in the destination folder. The program replaces the target file with the temporary one only after the copy operation is successfully completed. So, in the case of a connection failure, only the temporary file is affected. Just synchronize again when the connection is restored.

How does the application handle deleted files and folders?

Allway Sync recognizes that you deleted a file or a folder from one location and deletes it from the other. You can optionally disable propagation of file deletions. See more details in the Synchronization Algorithm Description.

Why does my spyware-protection application say that Allway Sync may contain spyware?

Allway Sync may be configured to check for software updates from time to time. Because this activity is similar to that of some malicious software, the spyware-protection package is warning you that there may be a problem. Rest assured that no personal information is sent over the Internet at update checks, as provided in our end user license agreement.

What type of data can be synchronized?

See our article on Synchronization Data Types.

How do I synchronize two computers using a USB drive?

See our article on Removable Device Synchronization.

Sometimes Windows assigns different drive letters to my USB devices. How do I set up Allway Sync to synchronize with a specific device?

Insert the USB drive. Go to Control Panel/Administrative Tools/Computer Management. Select Disk Management. Point at the drive you just inserted and right-click the mouse. From the context menu that appears, select the option to change the drive letter. In the Change Drive Letter dialog, select an available letter for the drive. Now, every time you insert that USB drive, Windows assigns the drive letter you specified.

Where can I get an FTP or WebDAV account that I can use to synchronize with over the Internet?

There are a number of data hosting solutions available. For North American and European customers we recommend 1&1 Web Host as a fast, reliable and affordable service. FTP plans start at $4.99 per month, but we suggest signing up for an account with Microsoft SharePoint capabilities (starting at $19.99). With SharePoint hosting you can download, upload, manage and share your files from any PC (Internet Explorer 5.0+ supports WebDAV). You also get complete integration with Microsoft Office, Lotus Notes, Macromedia products and much more (see 1&1). Use Allway Sync to synchronize local drives with a SharePoint server over a secure connection (WebDAV over SSL). See the topic above for details on how to synchronize with a WebDAV server.

Why does Allway Sync mark some changed files as "Questionable"?

This behavior is by design. Because we value your data, we use an algorithm that guarantees you won't lose your files even if the file modification time is wrong (generally because of an incorrect computer system clock). To do so we need to collect information from all of the devices you synchronize. So, you need to run Allway Sync once on every computer. After that it can be sure where the most recent version of a file is. Before that information is available, Allway Sync can only compare file modification times, which can be inaccurate. Under these circumstances, Allway Sync asks the user to confirm its decision. See more details in the algorithm description.

What is the "_SYNCAPP" folder that has appeared on my drives?

This folder contains the synchronization database that is required for proper algorithm function without user assistance.

I'm doing a massive backup. When it gets up to around XXX,000 files analyzed, it crashes. Why?

This happens because the synchronization application ran out of memory. Our sophisticated sync algorithm must collect a certain amount of data for each file. This can result in the consumption of a lot of memory if your synchronization task involves many files. Eventually, memory runs out and the program can't continue. To work around this problem, try to keep files that might be modified (and so need to be synchronized) separate from those that are static (software distributions, program folders) and exclude the latter from synchronization.

Why do the "analyze" or "synchronize" processes not finish?

Synchronizer has errors and warnings handling pages that contain settings of synchronizer's behavior at the moment error/warning appearing. In the Options window navigate to and select the Profile Settings > [Job name] > Error handling menu item. By default, in manual mode most types of warnings/errors have "Alert" setting. In this case the program stops all acts till you have made decisions for all questions about warnings/errors. You can change the software behavior by choosing of "Ignore" or "Skip" . After this, "analyze" and "synchronize" processes will work by design without error and warning messages.

How do I synchronize Outlook Express e-mail messages between home and work computers using a USB drive?

Setup and configure OE on both computers. Exit OE application on home computer. Start OE on work computer. Send and received e-mail during your normal business day. Before heading home, exit OE application on your work computer and start Allway Sync. In the left sync panel browser for the following folder: C:\Documents and Settings\<your user name>\Local Settings\Application Data\Identities\{<OE identity>}\Microsoft\Outlook Express In the right sync panel type <USB drive letter>:\OE. Press "Synchronize". Take the USB drive home. Make sure OE is not running on your home computer. Start Allway Sync and configure it the same way as you did on your work computer (see above). Press "Synchronize". Start OE. You should see all the messages from your work computer. Send and received messages, exit OE, synchronize with Allway Sync and take the USB drive to work. And so on.

How do I synchronize MS Outlook on a laptop and a desktop over a local network?

Microsoft Outlook keeps all your e-mail messages, contacts, appointments, etc in the following file:
for XP users: C:\Documents and Settings\<your user name>\Local Settings\Application Data\Microsoft\Outlook\Outlook.pst
for Vista users: C:\Users\<your user name>\AppData\Local\Microsoft\Outlook\Outlook.pst
Here's an example how you can keep Outlook instances on two machines in sync. Setup and configure Microsoft Outlook on both computers. Install Allway Sync on the laptop. Make Outlook folder accessible by network users on the desktop computer. To do so, locate C:\Documents and Settings\<your user name>\Local Settings\Application Data\Microsoft\Outlook\ in Windows Explorer, and right click on it, select "Sharing", click "Share this folder" and set "Full control" permission for all users (if the last option is available). Make sure Outlook application is not running on both computers, go to the laptop and start Allway Sync. Specify C:\Documents and Settings\<your user name>\Local Settings\Application Data\Microsoft\Outlook\ folder on the laptop in the left sync panel. Browser for network share you've just created in the right sync panel. Press "Synchronize". Now Outlook data are identical on both machines and you can work with Outlook application on any of two computers. When it time to switch a computer, exit Outlook, start Allway Sync on the laptop and synchronize again. And so on.

Why does Allway Sync fail to copy files that are currently locked by other processes, which are usually .pst and database files?

Allway Sync doesn't copy locked files by design to guarantee data integrity. User have to exit the application that is using those files (Outlook, for instance) to make synchronization possible.

I'm receiving the following error message when trying to synchronize ACT! files "The process cannot access the file because it is being used by another process". Why?

Unfortunately, ACT! (and a few other applications) install an MSSQL system service that is active even when the ACT! application is not running. That's why you receive the error message above. To be able to synchronize ACT! database files you need to stop the MSSQL ACT! service temporarily. Go to Start/Control Panel/Administrative Tools/Services, locate the service named "MSSQL$ACT7" (or similar), and stop it, Then, synchronize data and restart the service. Alternatively, you can permanently exclude ACT! files from synchronization in the Allway Sync View/Options window.

Is it possible to transfer/backup the sync job configurations?

The simplest way is to use Import/Export menu items from File menu.
Another way: synchronization profile is stored in the following location:
<Application Data folder>\Sync App Settings\_SYNC.APP\default profile.xml
where <Application Data folder> is usually C:\Documents and Settings\<your user name>\Application Data
or C:\Users\<your user name>\Application Data
Just copy this file for backup and to transfer your settings to another machine.

When I sync "My documents" on multiple computers where my logins are different usernames before synchronization start I always need to change root folders manually. What can I do around this?

For example, you want to sync to multiple computers where your logins are different usernames, i.e. you log in as user names: 'FirstName' on one computer, 'SecondName' on a second, 'ThirdName' on a third.

So if you setup Sync 'n' Go when logged in to the first computer as 'FirstName', the USB drive syncs in the file system to 'C:\Documents and Settings\FirstName\My Documents\USB Drive'. Then, when you take your USB drive to the second computer, the USB drive still gets sync'd to 'C:\Documents and Settings\FirstName\My Documents\USB Drive', when you would have expected it to sync to 'C:\Documents and Settings\SecondName\My Documents\USB Drive'. To work around this, You can use the USERPROFILE environment variable and manually type in '%USERPROFILE%\My Documents\USB Drive' as the sync to folder.

Let's complicate a problem and assume that on the third computer 'My Documents' is located on a network share '\NetworkShareThirdName' and the USERPROFILE does not point to that location (it points to 'C:\Documents and Settings\ThirdName'). To work around this, You can create a new user environment variable on all 3 computers:
On the desktop, right click 'My Computer' and select 'Properties',
On the 'Advanced' tab, click 'Environment Variables',
In the 'User variables' section, click new.
In the 'Variable name:' box, type 'MYDOCUMENTS',
In the 'Variable value:' box:
- If the My Documents folder is on the local drive type:'%USERPROFILE%\My Documents',
- If the My Documents folder is on a network share type:'\NetworkShareThirdName'.
Click 'OK' 3 times (until the computer properties window closes).
In the Allway Sync 'n' Go application click in the text box of the sync to folder and manually type '%MYDOCUMENTS%\USB Drive' and click 'OK'.

The environment variable way is good but it has one restriction - administrator's rights are needed to use it. The next way turns off this limitation for the following file folders: 'my documents', 'my music', 'my video', 'my pictures'.

Just click in the text box of the folder selection panel and manually type 'my documents', 'my music', 'my video' or 'my pictures' in angular brackets and click 'OK'.

If you want to sync the same folders but for all users use 'all documents', 'all music', 'all video' and 'all pictures' notation.

Can I sync the contents of the files like text lines, database records, archive content etc.?

AllwaySync synchronizes whole files only. It does not read the file to interpret what's inside the file. It does not merge the parts of different versions of the same file into a new copy of the file. It just defines what version of the file will be copied to replace another version. The file is a minimal unit of the information for synchronization process.

For example: AllwaySync cannot sync individual contacts or emails stored inside "Outlook.pst" file, because it does not know what's inside the file.

My FTP Server has some issues during synchronization. Can I fix them?

Currently there are many FTP servers released by many software companies and the independent developers. Unfortunately despite the FTP has the regulated standards different Servers have different behaviour during file time stamps making.

To avoid this problem the synchronizer has own files' time stamps which it keeps in metadata file with synchronization history.

To create these time stamps the synchronizer requires the first synchronization should be performed/processed by synchronizer only (not by the files' copying manually). This way guarantees that the synchronizer knows the files are equal even if the file system data stamps are different.

If during first synchronization all the synced files were copied but because of some circumstances the metadata file was not written to FTP root sync folder next time the synchronizer tries to repeat the first synchronization and all files copied on FTP server's side can be recognized by synchronizer as not equal to files located in local folder.

By design the synchronizer copies the file into temporal folder and only then renames and moves it to the destination folder. It is the way to be sure that the file was copied completely. Some servers do not support files renaming and moving of file if the source folder and destination folder are not the same.

Usually we use FileZilla FTP server and recommend this server to our users for using with the synchronizer.

The synchronizer has not any tools to make changes in a network bandwidth. It also can not resume of broken uploads/downloads.

I'm trying to sync with FTP Server and some national characters in file names are displaying incorrectly. How can I fix that?

Firstly please make sure FTP Server you are working with supports UTF-8 mode and UTF-8 is enabled in server settings. UTF-8 mode should also be enabled in AllwaySync FTP Wizard Settings (The panel which you specify username and password in).

In the second check the system locale settings. Language Settings Format and System Locale should match. Open Control Panel->Regional and Language Options and make sure you have the same selected Language on 'Formats' and 'Administrative' tabs.

GUI window is empty. How can I fix that?

Problem description:
After install (and also after repetitive install) screens are completely empty - all windows are empty, all functional buttons are greyed out (ie. analyze, sync all, copy, paste etc) - option fields are also all empty.

Please open windows registry with "regedit" software. Find registry branch "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\". By design five zones should exist in this branch (0,1,2,3,4). Delete extra (parasite) zone with a pseudo-graphic number. Usually you can see it before zone number 0.

Does synchronizer have ability to encrypt files/folders before synchronization?

You have ability to encrypt each file before synchronization. Synchronizer has "Compression and encryption" option that allows to encrypt each of files separately in its individual archive file. This option can be applied to any of supported synchronization folder types.

To implement encryption please choose synchronization folder and then click the "Configure..." button. Find a "Compression and encryption" item in opened window and set it into "Compress and encrypt files". After it you will be requested to input encryption password which will be used for your files' access.
