HashMyFiles by nirsoft offers both those options BTW. My most frequent use for hashing programs is finding duplicates. Si I'm using HashMyFiles. It also has a add to context menu option.

RapidCRC Unicode v0.3.39 Updated

Andrew Lee on 6 Feb 2024
  • 868KB (uncompressed)
  • Released on 1 Feb 2024
  • 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-1/256/512 and Blake2sp.

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.

shoover on 2016-02-21 09:17

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

MultiPar v1.3.2.9

Andrew Lee on 3 Sep 2023
  • 2MB (uncompressed)
  • Released on 30 Aug 2023
  • Suggested by MarkyMark

MultiPar helps protect backups and transfers with error detection and recovery. The program looks at information from any number of files and folders to function as insurance against data loss. The program generates companion "PAR" files that are built from a percentage of the originals, using more space for greater protection (e.g. 10% of the original for already safe methods, 50% for frequent failures).

The program has a wide variety of customizations including format, processor usage, and various other tools available to the standard PAR format. For backups, it can also choose PAR size by available free space (e.g. saving a 3 gig file to a 4.7 gig DVD will mean generating a 1.7 gig PAR file).

Functional in Linux/Mac via WINE. The program supports multi-threading, multiple processors, can recurse subfolders, and functions with standard formats including PAR, PAR2, and (experimental) PAR3 formats.

From the author of Multipar:
BEWARE: multipar . eu is a malicious spam site with altered versions of MultiPar.

You should remove all links to it to reduce the Google rating.

@Multiparuser: if you go to the page we link to when you click "website" you can see what the author has posted about the .EU mirror, which is encouraging caution. He does not call it a malicious spam site.

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/-256/-512/-384. The various hashing information can be saved to a report (text/HTML/XML/CSV/TSV) that includes name, path, dates, file size, version and other info.

Blows my mind how stagnate NirSoft's programs become, HashMyFiles still doesn't have a way to "Delete files to Recycle Bin" or similar. And all his programs are still plagued with DPI/multi-monitor issues years after reporting about them.

Fix was about "Explorer context menu" which have absolutely nothing to do with TPFC, so I dared to omit such details

Now what we need is a way to generate hashes for all files
in directories

abc on 2012-06-09 04:33

Needs support for SHA-2 (SHA-224, SHA-256, SHA-384, and SHA-512), it's becoming more common now days. The interface is quite good though

den4b on 2014-02-20 21:32

I just wanted to let you know that your suggestions have been heard and implemented.

@ Jon: Latest version can compute multiple hashes simultaneously.

@ abc: SHA-256 and SHA-512 have been added in the latest version.

I agree that HashMyFiles is the best one for multiple files I have found to date. It's small, quick and even integrates into the right click menu if you want it there.

Works great to create/verify companion hashes for individual files. Wish there was a way to work in a batch mode.

Very minimal indeed -- doesn't take command line input (e.g., 'pockethash somefile.exe'), produces no output other than what it shows in GUI. The saving grace is its VirusTotal integration.
