Designed and developed by an entity called MOGware, this utility is a free to use software application that is intended to help users maintain multiple versions of their files as changes are being saved. FileHamster is intended to help users working on projects to maintain the pre-edit versions so that they can revert to the older versions when required. With this tool, you will be able to execute incremental backups as and when changes are implemented in your files. It also offers the option to save notes related to the changes that are being made in a file. You can implement this utility in Windows 2000, 7, XP, and Vista versions.
