Gemini is a northern constellation also known as “The Twins.” Duplicate files are very much like “twins” and “eggs,” so we have used these images and the name Gemini.
After you have successfully installed and launched Gemini, drag the folder or drive you wish to scan to Gemini and drop it on the Gemini window to start scanning it for duplicates.
When you’ve scanned a certain folder for duplicates and checked off the necessary files for deletion, click Remove Selected to delete them. After doing so, Gemini will show you the list of chosen duplicates so you that you can recheck everything. Click Remove Duplicates if you have double-checked the list and Gemini will then move them to the Trash in spectacular fashion by shredding the list before your eyes. It’s quite cool.
Gemini only moves duplicates to the Trash. It does not actually erase them. You can always go to the Trash and restore the necessary duplicates.
Yes. Command-click the folders in Finder that you wish to be scanned to select them all at once and then drag and drop them on Gemini window. Note that though Gemini’s scanning is fast and efficient, the more folders you select to scan, the more time it will take to scan them.
Yes. You can either drag them from Finder and drop them on the Gemini window, or select them in a new Finder window that will appear after you click “+” button.
Yes. If you have files in your iPhoto, iTunes, Aperture or Photo Booth libraries, Gemini will scan them for duplicates. Be aware that in order to correctly remove duplicate files, specifically from your iTunes or iPhoto library, Gemini will launch iTunes or iPhoto to ensure that library corruption does not take place. Please remain patient when cleaning these libraries; it can take some time.
Gemini can find duplicate folders. These are folders that contain identical sets of files. However, sometimes a user can have similar folders, or the folders that are slightly different. Obviously, it is much easier to delete one of these folders than all the files it contains one by one. The ability to show similar folders is planned to be implemented in a future release of Gemini.
The Auto-select algorithm analyzes file parameters, such as dates of creation and modification, folders they are placed in, and others. Based on the above, Gemini defines what instances of files look like duplicates. The Auto-select feature always leaves one instance of every file untouched meaning that it is completely safe to use.
Gemini is 100% safe to use. Its scanning algorithms avoid scanning for vital system files. You can rest assured that you won't remove files that can affect your system performance. Also, if you delete duplicates with Gemini, you will still be able to restore them because Gemini does not erase these files, it only moves them to the Trash.
The pie chart shows which categories of duplicates take up the most space. You can click on parts of the pie chart to filter the duplicates and (if needed) quickly locate and delete the most space-consuming files.
If the file is being used by a system process or your user account doesn’t have the proper permissions to delete it, the file won’t be removed by Gemini. This is why it continues to appear in your scan results.
Gemini has a limitation on number of duplicates that are shown in the duplicate list. It is designed this way to prevent you from getting lost in dozens of small duplicates that require time to be examined. If the number of found duplicates exceeds the acceptable limit, Gemini will show only the largest duplicates that were found.
When you clean duplicates with Gemini, the app moves them to the Trash. This allows you to restore the files in case you accidentally delete something. However, if you are certain that you don’t need the deleted files, just empty your Trash and the free space on your drive will be increased.
