Checksum Folders

Checksum Folders calculates and compares the checksums of all files in a folder and it’s subfolders. You can export the results as a text or CSV file.

WHY CHECKSUMS ARE USEFUL
• Is my backup working?
Compare an important folder on your harddisk or SSD with it’s backed up version.
• Is my harddisk or SSD damaged?
Compare a folder on your harddisk or SSD with an earlier version from a year ago.
• Is my RAM corrupt?
Compare a larger folder with it’s duplicate.
• Is my folder copy forensically sound?
Compare your copy with the original files and export your results.

FEATURES
• Calculates and creates a list of checksums of all files in a folder and it’s subfolders.
• Compares (if needed) two folders and checks if they are identical.
• You can interrupt your calculation or check, save your progress and continue another day.
• You can save your completed calculation results and check them against another (or the same) folder later.
• Export your results (just calculation or calculation & check) as a textfile or as a spreadsheet compatible CSV file.
• Supported checksum algorithms are MD5 (faster) and SHA 1 (cryptographically more robust).
• Shows the calculation progress of large files and the folder as a whole.
• Uses a speed and memory efficient computation and data storage model.
• Supports drag and drop.
• 100% hand crafted native Mac application.

Tip 1: Store your Checksum Folders’ savefile within your backup. Now you can check the integrity of your backup whenever needed.

Tip 2: If you just want to calculate single checksums or if you want to compare a file with it’s checksum on a webpage, please take a look at Checksum Utility in the Mac App Store, it is made specifically for this purpose, for single files.
