What is a .STG file?

The file extension .STG is associated with an ActiveSync Backup File. This type of file is created by Microsoft ActiveSync, which is a software program designed to synchronize data between personal computers and mobile devices. The .STG file contains a complete backup of the mobile device's data, including important information such as contacts, notes, and calendar entries. These backup files are often named "backup.stg." To view or manage the contents of a .STG file, you can use Microsoft ActiveSync. However, it's important to note that Microsoft removed the backup and restore functionality from ActiveSync starting with version 4.2. Therefore, if you need to restore data from a .STG file, you should use Microsoft ActiveSync version 4.0 or an earlier version that supports .STG files.

Additionally, there is a specific tool called ActiveSync Backup File Restorer that can also be used to open and restore data from .STG files. This tool is particularly useful if you are working with versions of ActiveSync that no longer support direct backup and restore functions.

In summary, if you have a .STG file, you will need to use either an older version of Microsoft ActiveSync (version 4.0 or earlier) or the ActiveSync Backup File Restorer program to access or restore the data contained in the file.
