HOW TO Remove duplicates with AntiTwin

1

SELECT HARD DRIVE Open AntiTwin. Click “Select folder” next to “Basic folder” to select the root of your drive if you’re looking to clear up space on one drive only. Check “2nd folder” to select another folder path or drive if you’re looking to clear space across two hard drives by weeding out duplicates.

2

FOCUS SEARCH Leave “Include subfolders” checked and click “File filter.” You can exclude smaller files from the search (and speed it up) by setting a minimum file size. Click the drop-down as shown to focus on specific file types, and check “Compare images (pixels)” to look for visually similar images.

3

PICK YOUR COMPARISON METHOD By default, files are compared according to their content only, but you can also compare by name and file size if you wish. The “Match min” figure enables you to match similar, but not identical, files—this is best left for image searches only. Once done, click “Search.”

4

WAIT FOR SCAN A progress window appears – don’t be surprised to see it freeze occasionally as files are checked. You can pause or cancel the search at any time. After the folder contents have been read, files are compared to see which are duplicates and (if selected) close matches.

5

REVIEW RESULTS If you chose two paths, read the warning, but click “OK” as this would only be an issue if they were both pointing to the same folder. A list of all duplicates and similar files is shown, grouped together. Images can be compared by selecting one to reveal a pop-up window.

REMOVE DUPLICATES Right-click a file to decide whether to keep or remove it – you’ll also see options that enable you to mark specific folders as duplicates (see main text). After making your selections, use the legend to verify you’ve picked the right files to delete before clicking “Delete selected files.”
