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.
