VersionBox is a backup software application written for Windows operating systems. It helps to create the consecutive backup copies of the project file or directory into the special folder. Either the file or the directory backup copy is a Zip archive and gets the individual name which is the original project name joined with the date and time copy create. The backup copies of the directory can be contained both all files (full copy) and changed ones only (delta copy). It is possible to add the archive commentary or to confer the version number for the present state of the design.
