Yes, Amber provides file versioning. File versioning is a built-in feature for “VPHome” folder, it allows the user to recover files he might have accidentally deleted, or restore a modified document to an earlier version. You can have unlimited (limited by the disk space) version of each file stored inside VPHome to up to a maximum of 30 days. To get more information on how this work you can view our "What is the VPHome Folder" Help Center article.
Note: File versioning will consume storage from your device so the amount of version will depend on the amount of space left on your Amber.
