Remove duplicate files and similar images in three easy steps:

1. Choose search options and press Search button.

You can search for either exact duplicates (100% byte-to-byte match is ensured by the special hash function) or similar images (Detwinner generates groups of images that look alike using similarity level specified by you). You can also narrow your search by specifying file dates, attributes and masks.

2. Review found duplicates and select files to be removed.

Smart and regexp-based selection tools provide numerous options for batch selection of files that should be deleted. Instant preview allows you to be confident in your choice.

3. Press Delete button.

Files can be deleted permanently, to Recycle Bin or moved to the backup folder.
