Make sure you have Qt5 and its development libraries installed. Run "qmake" and then "make". You can also use QtCreator to compile it.
Note: This is an early version, it might have bugs, and due to the way it works (it simply takes a copy of the files one by one) the backups might occasionally be corrupted if the save files are modified in quick succession for example.
Click "browse..." button under "backup path" to set the path in which the screenshots and backups will be saved.
Click "browse..." button under "savegame location" and set the path which contains the files you want to create automatic snapshots/backups of.
Under "save pattern" enter the pattern of filenames that should be watched and backed up. Wildcards like * can be used. Examples are * for all files, quicksave* for all files starting with "quicksave".
Click "start" to start monitoring the specified files for changes.
Snapshots along with the screenshots captured will appear on the list on the right side.
Double-click a screenshot to view it larger in a separate window.
Click "restore" to restore a selected backup.
