Content comparison type

1. Content comparison type
Changes the method that Duplicate Cleaner uses to compare files:
 
  • Byte-to-byte (Compares all identically sized files against the other on a byte-by-byte basis)
  • MD5 (Hash algorithm -fastest)
  • SHA-1 (Hash algorithm - slower)
  • SHA-256 (Hash algorithm -slowest)
 
Hash algorithms generate a 'fingerprint' for each file. These are then compared for duplicates. More info here.

Long path support

4. Long path support
Support for long (>260 character) path names. Note that Windows' own support for these is patchy. (Long file names cannot be deleted in the Recycle bin for instance).
5

Zip file space

5. Zip file space
The maximum amount of temporary space Duplicate Cleaner is to use when unzipping archives for scanning. Having too small an amount available may slow down the scanning of zip archives.
