ilSFV

Files have a lot more going on than what you can tell by content, or extension. Behind all functionality traits, there are tons of type of code by which the computer itself recognizes the file. Some are used to fix critical areas, while other to verify integrity, which is exactly the case with ilSFV, with operations perform using various algorithms.

The application isn’t quite your usual checksum verifier, in the initial sense that you must load an entire folder for processing, unlike most apps of its kind only ask for a file. What’s neat about it is that the algorithm choice is built inside the open dialog, with three different ones for SFV, MD5, and SHA-1. Although not abundant, these are pretty popular checksum types.

It usually doesn’t take a lot of time for the application to finish file analysis, but this mostly depends on the number of files you load. Chances are not all files turn out to be in proper shape, and this can easily be seen through color differentiation of process result. You instantly know when a file is OK, bad, not found, or unknown.

The configuration panel allows you to set custom rules for when you encounter these situations. Tags can be added automatically, and even exceptions in the browse list for these file types, so no time is wasted when performing a new scan of the same source.

Extra tools can be used to find and remove duplicate files based on their checksums. There’s the possibility to truncate a file name by writing down the total number of characters a name can be fitted with. Sadly, there’s no option to generate a report directly to file. However, a comments tab shows all events, with options to customize messages, and have different values sent to clipboard for one, multiple, or all files.

Taking everything into consideration, we can state that ilSFV is a powerful checksum verification application, especially useful for verifying multiple files at a time. Even though there are only a few supported checksum algorithms, ease of use, and overall intuitive layout make the application at least worth a try.
