haha this is great, out of my own experience i feel obligated to admonish that this application is entirely identical to the other version created by the developer, "ipackr." I had been perplexed as to what the differences of the two were while I was searching for a simple gui for compression rather than using command line, and until recently when the application was released free for a limited time, I was still left without answers. It wasn't until I had both applications open in a double pane view when I realized the extent of their similarity. In conclusion, the application gets the job done efficiently, however, I feel consumers should should be more aware of how the applications are distinguished in more extensive detail
