  • 787KB (uncompressed)
  • Released on 1 Oct 2017
  • Suggested by Userfriendly

RapidCRC Unicode is a hashing program capable of checking and verifying the integrity of files, folders, or whole drives. The program includes process priority, ability to pause/resume analysis, job queuing, easily copy hashes to the clipboard and multi-threaded checks. If using checksum files (e.g. .sfv or .md5) for future verification, options include the ability to generate for every analyzed file, directory, or a single checksum with all hash data.

Includes direct support for CRC hashing in the filename (common for anime releases) for example: "MyFile [45DEF3A0].avi") Other algorithms range from fast to secure, including SFV(CRC32), MD5, ED2K, SHA-1, SHA-256 and SHA-512.

A 64-bit version is available on download page. Based on the original RapidCRC but updated with extended unicode support.

This is currently my go-to program. I tend to add it to the "send to" menu on machines I'm currently using and it works beautifully to check one or more files. Also, the ability to insert the hash directly into the file name makes so much sense. Just drag-and-drop it into the window and instantly know if there's a problem. Great solution to the multi-step check.

I think there is something wrong with the "CRC into Filename" function. This occurs with files that lack a file extension.

HashMyFiles is a small utility that allows you to generate unique file identifiers (hashes) using a variety of popular checks. These can help determine if a file has been modified or corrupted, as well as help determine the file's reputation by submitting to the VirusTotal database for malware analysis.

Formats supported range form fast to secure with CRC32, MD5, SHA1, SHA256, SHA384 and SHA512. The various hashing information can be saved to a report (text/html/xml) that includes name, path, dates, file size, version, and other info.

One cannot copy "SHA-384" and "SHA-512" values from context menu or via a hot key- to get "SHA-384" and "SHA-512" values one have to save to file ("Save Selected Items Ctrl+S") which is awkward.

How about dropping a gentle hint to nirsofer@yahoo.com ?

"How about dropping a gentle hint to nirsofer@yahoo.com ?"
If someone does this I will appreciate- I remember that long time ago I messaged NirSoft about something and since I got no response I will not try again. More- lately I am not in a very gentle mood. ;)
