The Duplicate Finder uses SHA1 checksum for file compare, only files with the same checksum are duplicates. This means:

“SHA-1 is essentially a secure checksum for a data file. The SHA-1 checksum is based on a cryptographic standard. For a given file, SHA-1 produces a 160 bit encrypted output known as a “message digest.” It is highly improbable that a modified data set would produce the same message digest. If a file is changed during transit, its message digest also changes.” – read more
