# Step 4. Select duplicates for removal

To simplify the decision-making process, you can take advantage of Gemini’s automatic selection filters. The filters can either be applied to entire groups, or to all duplicate instances of a particular file. Gemini provides the following selection filters (criteria):

Selection filter | What it does
Deselect All | Deselects all files of a certain group of duplicates.
Automatically | Uses its smart algorithm to select files that are most likely unneeded: old, rarely used, etc.
Newest | Selects duplicates with the most recent modification date.
Oldest | Selects duplicates with the oldest modification date.
Any | Keeps one random duplicate and selects all the other for removal.
Manual | This filter state is applied if you select unneeded copies manually.

Apply selection filters to an entire group: Click on the Select Duplicates/Similars menu and choose a desired filter.

Apply selection filters to duplicates of a certain file: Click on the found/selected counter and choose a desired filter.

Select a file manually: Select the checkbox next to a file you want to remove.

Note: When you try to select the last instance of a file, Gemini requests your confirmation. Select the Remove Last Instance checkbox to select all copies of a particular file for removal.

Select all duplicates in a certain folder: Click on the Select Duplicates/Similars menu and choose Deselect All, then control-click the folder you’d like to free from duplicates and choose Select All Copies Within “folderName” from its shortcut menu.

Deselect all duplicates of a group: Switch to the desired group of duplicates/similars (for example, Audio or All Duplicates). Click on the Select Duplicates/Similars menu and choose Deselect All.

Deselect all duplicates of a certain file: Click on the found/selected counter, and choose Deselect All.
