After you have successfully installed and launched Gemini, drag the desired folder or drive from Finder and drop it on the Gemini window. Then click the Scan button to start scanning the chosen location for duplicates.
Gemini is totally safe to use. Its algorithms avoid scanning critically important system files so you may be sure you won't remove files that can affect system performance.
Also, if you delete the duplicates with Gemini, you will still be able to restore them, as Gemini does not erase these files by default, it only puts them to Trash.
Auto Select algorithm analyzes file parameters, such as dates of creation and modification, folders they are placed in and others. Based on these parameters Gemini defines what instances of files look like duplicates. Since Auto Select feature always leaves one instance of every file untouched, it is completely safe to use.
By default, when you clean duplicates with Gemini, the app moves them to Trash so you can easily restore them. If you are sure you don’t need the deleted files, just empty your Trash and free space on your drive will be increased.
However, you can go to Gemini's preferences and set it to erase files completely instead of trashing them.
When you’ve scanned a certain folder for duplicates and checked the necessary ones for deletion, click Remove Selected to delete them. After that Gemini will show you the list of chosen duplicates so you could recheck everything. Click Remove Duplicates if you are sure and Gemini will move them to Trash by spectacularly shredding the list.
Pie chart shows which categories of duplicates take most space. You can click the parts of pie chart to filter the duplicates and (if needed) quickly locate and delete the most space-consuming files.
Since Gemini only moves duplicates to Trash (and not physically erases them), you can always go to Trash and restore the necessary duplicates.
Yes. Command-click the folders in Finder you want to be scanned to choose them all and drag and drop them on Gemini window. Note that though our scanning is really fast and efficient, the more folders you want to scan the more time it will take to scan them.
Yes. You can either drag them from Finder and drop on Gemini window, or choose them in a new Finder window that will appear after you click the “+” button.
If the file is being used by a system process or your user account doesn’t have proper rights to delete it, the file won’t be removed by Gemini. That is why it continues to appear in scan results.
Most probably some of the found files were too small to be listed, so after the rescan they may be showed as the only duplicates that were not deleted yet.
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 such folders than all the files it contains one by one. The ability to show similar folders is planned to be implemented in next releases of Gemini.
Gemini is a northern constellation also known as the Twins. Duplicate files are as much the same as the twins and the eggs, so we have used those images in the teaser and name.
If you have files in your iPhoto, iTunes, Aperture or Photo Booth libraries, Gemini will scan them for duplicates. Starting from version 1.3, Gemini can also remove duplicates from your photo libraries. During the removal process Gemini may launch your library and relaunch it in order for changes to be applied, so rest assured this is an expected behavior.
In very rare cases you may find that Gemini finds less duplicates in your photo library than you think you have. Actually, Gemini finds all of them, but then the potentially troublesome dublicates are being filtered and excluded from scan results in order to prevent any unexpected consequences, such as library corruption or inability to find original photos.
You can uninstall Gemini like any other Mac application, just drag the icon from the Application folder to Trash.
