Recently, I reviewed another software: Gemini 2. You know, as a sign of the zodiac Gemini is the sign for twin and that seems to be the reason for the name.
Each owner of a computer knows the problem of constantly shrinking free space on the internal disk. Not only new files occupy the precious disk space, but also duplicate files are consuming space. Gemini 2 should help one to reclaim the space occupied by unnecessary doublets.
After starting the program it asks for permission to your user folder and then starts scanning for doublets
When finished it presents a summary slide showing how much space probably could be reclaimed.
But, don’t trust this! Check the found doublets very carefully which one of the doublets could be deleted without causing problems. It scans the folders as well as your iTunes-library and the photo-mediathek. So, it finds i.e. photos exported from your photo-mediathek to the disk, when they are still in the mediathek as well.
Just in case, you want to try it on your own computer, there’s a free trial version available.
