Changes Saver is intended for saving the files modification history. At each file modification, its copy, that is its version, gets created. A user can view and use any previous file version at any moment. Changes Saver allows setting different options of versions creation, which are: Modes of versions creation. It is possible to create a version at each saving, after accumulating a certain number of modifications, or after a certain time interval. Besides, a user can manually create versions when he/she finds it necessary. Versions storing. There is a possibility to set a number of versions for storing, or a period, for which versions will be saved. This does not mean, however, that after these conditions are reached, versions will no longer be created. What is going to happen is that old versions will be replaced by more recent file versions. Versions naming. You can set a format of file names for versions. This is convenient for viewing versions. · Alternative viewer. It is possible to set a program for viewing versions, different from the one defined in Windows. This can be helpful in the situation when it is necessary to simply view a version file without loading a “heavy” application for its editing. Change Saver provides with the ability to manage files versioning from a special application Changes Saver Monitor, as well as directly from Windows Explorer context menu, which greatly simplifies working with Changes Saver.
