fck - A simple checksum utility that just works

File checker (fck) is a python wrapper for various checksum functions (though right now it only supports CRC32). It's goal is to make verifying large amounts of files both easier and faster.

Features

• Process/check multiple files at once.
• Automatically find expected checksums
• Quickly find faulty files.
• (Not yet) easily extendable

Syntax

fck --help
usage: fck [-h] [-b] [-p PROCESSES] [-c CHECKSFV] [files [files ...]]

Calculate CRC32 of files

positional arguments:
  files                 files and folders to process

optional arguments:
  -h, --help            show this help message and exit
  -b, --bigfiles        parse files that exceed your memory limit
  -p PROCESSES, --processes PROCESSES
  -c CHECKSFV, --checksfv CHECKSFV

Dependencies

• = Python3.8

• zlib // used to calculate CRC32 sums

Roadmap

0.1

• Context based selection of apropriate checksum type.
• Define and document project/class structure.
• Support reading/writing '.sfv' files.
• Add Tests.

0.2

• Dehardcode various CRC32 specific functionalities.
• Implement propper logging.
• Implement other common checksum types.
• Write a comprehensive documentation.

Future

• More and better error (and memory) handling.
• Better logging/output control.
• Add an optional GUI.
• Package application for Windows/Mac/Linux (maybe)
