I created a QlikView application that manages versions of the PRJ directory. In this application you can be generated versions, checkpoints and backups of the generated versions.
No need to create any new folder, performing reloading the application are generated automatically.
This application must be in the same folder as the folder PRJ.
You only need to type the name of the application that you want to control versions, without the extension, and have generated the PRJ folder. For example, for "Movies.qvw" application "Movies" will be written.
In addition, you can make comparisons of different versions of objects with WinMerge.
You need to have installed WinMerge and PowerShell to work properly.
I hope you find it useful.
