An example implementation of duplicate file detection using Python. This could be used as the backbone for a de-duplicated file system.
Compute file hashes
The file hashes are computed for a specified chunk size using either SHA256 or Blake cryptographic functions using the hashlib python library.
Detect file duplicates
Creates a dictionary output with the cryptographic hash as the key and a list of files that share that specific cryptographic hash as the value.
Find duplicates in a list of files
Finding the duplicate files can be performed by simply iterating over all the keys in the file comparison dictionary, looking for values with a list size of more than 1.
