HashMyFiles is a small utility that allows you to generate unique file identifiers (hashes) using a variety of different popular tools. File hashes can be submitted easily via the tool to VirusTotal for malware analysis.

Formats supported include CRC32, MD5, SHA1, 256, 384 and 512. The various hashing information can be saved to a report (text/html/xml) that includes name, path, dates, file size, version, and other info.

I dont see a forum link for this post, I also sent the author a report, testing this version (1.97) he still didnt fix it.
I agree that NirSoft utilities are a must have, i myself use few.
From my own experience, the author is lazy when it comes to feedback.

Anyway, to produce the bug...
-Drop a large file and sop the process before its complete, lets say at 2%
-Drop a small file and it will scan old file first.
Most likely he doesn't empty a variable when you break/stop the operation. Should be an easy fix.

@Ganamyde: Point taken. Thanks for the breakdown.

MD5 Checksum Tool v3.9.0.0 Updated

Checker on 23 Mar 2015
  • 8MB (uncompressed)
  • Released on 21 Mar 2015
  • Suggested by I am Baas

MD5 Checksum Tool generates a file checksum that can be used to check if a file has changed, usually to affirm it's legitimate and uncorrupted. The program can scan a folder and subfolders (recursively), as well as provide a report of all files, their size, and checksums.

The program will allow the comparison of two files with their respective checksums and supports MD5, SHA1, SHA256, SHA384 and SHA512 checksums.

A 64-bit version is available (within the x64 folder).

System Requirements: Win2K / WinXP / Vista / Win7
Writes settings to: None
Stealth: ? No. Writes EulaAccepted key in to the registry.
Unicode support: No
License: Freeware
How to extract: Download the ZIP package and extract to a folder of your choice. Launch MD5Checksum.exe.

There's no [portable] link anymore on the homepage (where other apps do) and I can verify that v2.8.0.0 writes it's setting to the registry.

dany on 2011-11-05 16:52

Disregard my previous comment, something screwed up my regShot. It only writes the EulaAccepted key to the registry. Not stealth and a little annoying but otherwise portable...

Couldn't get this to run reliably at all. Constant freezes; always had to kill it with Task Manager.

RapidCRC Unicode v0.3.16 Updated

webfork on 26 Apr 2015
  • 1MB (uncompressed)
  • Released on 24 Jan 2015
  • Suggested by Userfriendly

RapidCRC Unicode is a hashing program capable of checking files, folders, or whole drives. The program includes process priority inside the Window, ability to pause/resume analysis, copy hashes to the clipboard, job queuing, 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.

System Requirements: Win2K / WinXP / Vista / Win7 / Win8
Writes settings to: Application folder
Stealth: ? Yes
Unicode support: Yes
License: GPL
How to extract:
  1. Download the Archive or Archive (x64) RAR package and extract using 7-zip or similar program to a folder of your choice
  2. Create an empty text file called options_unicode.bin in the same folder
  3. Launch RapidCRC.exe
Optionally, delete rcrcshex.dll or rcrcshex64.dll for 64-bit version. Otherwise, this shell extension file will need to be manually registered with Regsvr32 to use.
Similar/alternative apps: FileVerifier++
What's new?
  • Fixed problems with empty base path, for example when hashing from search results.
  • Shellext: Register for all users, now works with builtin admin.
  • Fix hide verified in options dialog.
  • Automatically add hash extension in file dialog.

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.

MultiHasher v2.7.1 Updated

webfork on 21 May 2015
  • 7MB (uncompressed)
  • Released on 23 Jan 2015
  • Suggested by guinness

MultiHasher is a drag-and-drop tool for creating and checking file hashes, useful for checking data integrity. The program will check files, folders, and even text using a variety of methods with both pause and cancel options for large operations. The program can then compare digests to detect changes as well as query the result to the VirusTotal database. A search tool lets you quickly track down both files or specific hashes from long lists.

A recursive checking option (entire directory trees) is available in the options menu. The program can also use existing, standard hash files such as MHX, SFV, MD5Sum, etc. to check integrity.

Supports 64-bit operating systems and available algorithms include from fastest to most secure: CRC32, MD5, RIPEMD-160, SHA 1, 256, 384, and 512. Can include one, some, or all algorithms available in testing.

System Requirements: WinXP / Vista / Win7 / Win8

If you use category All Files it will make a .json file

bzl333 on 2014-04-04 19:53

it opens a browser for the VT results :(

PeStudio shows the results in its own GUI.

would be nice to have program like this that you enter a folder or partition of say all your portable apps and this program works slowly in the background at like 5% of CPU and checks all hashes against VT, option to upload those unknown, then stores to a small database and gives the option to recheck every so often against the hashes stored, etc. And option to select filetypes that dont need to be scanned. Would be a good security program.

I've been using this program a lot for the MD5/SHA1 and VirusTotal features for postings here on PFW. That said, I still prefer RapidCRC Unicode for hashing / checking lots of files.
