MultiHasher v2.9 Updated

  • 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.

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.

Two bugs to be aware of. The first bug is:
Make a new directory with some files in it. Drag the folder into MultiHasher and make MD5 hash calculations for all those files. Save the hash list in MultiHasher own hash format (mhx). Clear the list. Load the hash list. Drag the folder back into MultiHasher to "add" the folder. MultiHasher then hangs. Versions prior to worked fine.

With, a new major bug:
MultiHasher refuses to load mhx files that are over a certain size. From what I test so far, any mhx files that are larger than roughly 150 KB refuses to load when you drag and drop the mhx files into the MultiHasher window. Instead, MultiHasher will treat it as a regular file to be hashed rather than a list of hashes. If you tried to load the file manually (Ctrl+O), MultiHasher will do nothing for these files. Files that are less than 100 KB loads perfectly both ways.

Both bugs have been reported (1st bug about a year ago). However author never replied and even deleted the thread and my forum account. In other words, be aware of any potential new problems with new versions and always keep old versions.

These bugs does not occur if you use file formats other than their own mhx format.

Anyways, like Webfork, I now prefer RapidCRC Unicode over this. RapidCRC Unicode has been rock solid and all bugs that I have reported to the author were taken care of or were promptly responded to.

MultiPar v1.2.9.9 Updated

webfork on 2 Jan 2017
  • 2MB (uncompressed)
  • Released on 12 Dec 2016
  • 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.

System Requirements: WinXP / Vista / Win7 / Win8 / Win10
Writes settings to: Application folder; however shell integration and filetype associations will write to the registry.
Unicode support: Yes
License: GUI: Freeware (accepts donations). Console applications: GPL
How to extract:
  1. Download the ZIP package and extract to a folder of your choice
  2. Delete:
    • MultiParShlExt.dll
    • MultiParShlExt64.dll
    • MultiParShlExt.ini
    • Any unwanted language files
  3. Launch MultiPar.exe

RapidCRC Unicode v0.3.22 Updated

billon on 29 Dec 2016
  • 786KB (uncompressed)
  • Released on 29 Dec 2016
  • 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.

System Requirements: Win2K / WinXP / Vista / Win7 / Win8 / Win10

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.

shoover: The dev has been pretty responsive if you want to reach out:
