HashTab Shell Extension
IainB:
I couldn't find this version:
Just thought I'd revive this thread to say that I've been using HashTab (v5.1.23) for a while now and am finding it very useful in my file management tasks - e.g., when I am wanting to determine whether two files of the same or different names are in fact the same (duplicated) file.
However, I might dispense with using it on those occasions when the xplorer² Checksum column is likely to be more useful (see below).
Also:
* HashCheck Shell Extension: Thanks to @PhilB66's mention of it in this thread (above), I am about to trial this.
* WinMD5sum: I have been using this on occasion.
* xplorer² Checksum column:: is a column you can invoke in xplorer² to give you a checksum of files in (say) a directory listing. The manual warns that invoking the Checksum column could be a resource hog:
x² extracts certain information from each file and displays it in different columns of the folder pane (e.g. checksum).
However, this additional consumes CPU resources and slows down other operations.
To make the operation more efficient, x² has a provision that it will display the information only if the file-size is below a [settable] threshold value.

Spoiler Notes on HashTab Shell Extension (prepared using MS OneNote).
(Notes posted to DC Forum as this is such a useful Shell Extension.)
I wanted to install this very handy shell extension - which I have been using for ages - on an HP Pavilion-15 laptop (Win10-64 PRO), having last used it on the Toshiba-L855D under Win10-64 PRO. However, I could not find the setup proggie in my online Archive.
I couldn't recall where/when I I originally got this proggie, not could I find any notes in my OneNote Notebooks about this either, so I determined to make some notes (these) this time around.
I knew the setup proggie would be on my backup, but I thought it would probably be simpler/quicker to download it afresh from the Internet.
I was wrong.
• A duckgo search turned up a review (which I took a copy of) from 2010 on freewaregenius.com, which gave the source website as http://beeblebrox.org/
• However, that source had gone 404 and the domain was up for sale.
• I found the 2010 version 3.0 on Wayback: https://web.archive.org/web/20100620071934/http://beeblebrox.org/
- (which I also took a copy of) and downloaded the setup file from there:
https://web.archive.org/web/20100620071934/http://beeblebrox.org/HashTab%20Setup.exe
Then I took a cursory look over the years after 2010, and didn't find anything useful on Wayback.
One of the files (.dll) in the installer was dated 2009, so I figured the dl file was the latest version. I saved the setup file into my Archive and these notes, just in case.
File: HashTab v3.0 Setup (2010-06-20).exe
(The above links to the file in the Archive, and the file is also inserted
to the right of this note.)
When I ran the setup/installer it proved to be a quick, no-fuss affair.
The opening panel:
The opening panel led to an incredibly verbose licence agreement:
Then it wanted to install to C:\Program Files\HashTab Shell Extension
So I changed that to C:\UTIL\Explorer software\HashTab Shell Extension
- whereupon it installed 2 files ( a .dll and an .exe) and set itself into the Explorer Shell.
The download page gave MD5 hashes - this one for Windows setup:
HashTab Setup.exe: 5845F52D425C75E232B1AD5EE3B189A8 (windows)
So copied that hashkey, right-clicked the setup file, selected Properties-->File Hashes
and pasted the hashkey into the empty box Hash Comparison
The big fat green tick signified that HashTab had verified its own setup file's MD5 hashkey.
(Note the version and date towards the bottom of the box below.)

I did a Sherlock Holmes and think I have sorted it now.
Big footprints for anyone who wants to get at these versions of the same thing.
Spoiler Further notes on HashTab Shell Extension (prepared using MS OneNote).
After further investigating my archives and searching the Internet a bit more thoroughly, I think I have made sense of the versions.
1. beeblebrox.com v3.0 (2009) - this was from a now defunct website (404).
2. implebits.com v5.1.0.23 (2014-03-14) - this was in my Archives and came from http://implbits.com/HashTab/HashTabWindows.aspx (404) and I initially mistook it to mean that the domain was defunct, but when I checked, it wasn't defunct.
3. implebits.com v6.0.0.28 (2016-09-07) - this was the latest version on that domain.
So I now had 3 versions - 1 x beeblebrox and 2 x implbits. They seem to be the same things, probably developed by the same people. They certainly look the same, anyway.
The beeblebrox one is free, and the implbit ones are free for private use.
The main difference between the 3 versions seems to be, as shown below, in terms of the number of hashing algorithms that they can employ. Presumably, more is better, but it also makes the program files larger too.
The other main difference is in that the beeblebrox v3.0 has that nice friendly licence agreement, whereas the two implbits versions have the more unfortunate threatening licence agreements plus an angry warning that it is "Not Licenced for Commercial Use" (with title capitals like that).
If you asked me which I might prefer, I would probably plump for the beeblebrox one, because of its friendly licence agreement and its smaller footprint - I don't really require all those extra hashing algorithms.

Thanks. I have been using the 3.0 version for years, and the 2.0 version before that.
xtabber:
Gizmo's had a useful comparison of free hash check programs for Windows last year.
Not noted in that article is that HashCheck File Extension has been updated by a new developer to include SHA-256 and SHA-512, making it useful once again. The latest version (2.3.2 at this writing) is available here. It is also much lighter on resources and easier to use than most of the others, which is why I prefer it.
MilesAhead:
My MD5Hash program only does MD5 as one might expect from the title. But the main thing I wanted to accomplish was to make it robust for use with large files, such as video. I tested it with .mkv and .m2ts files 8+ GB in size and I never saw it crap out.
Unfortunately I lost the source code so I cannot fix a few niggling bugs. The main annoyance happens when you right click say 100 files in Explorer and select md5hash from the context menu(if you used the included utility that sets up context menu access.) There will be 4 or 5 copies open before the "single instance" behavior kicks in. I know how to fix it if I still had the source. But so it goes.
I regularly use it to check all the downloads on my page. The editbox is a RTF Edit control. So it can hold quite a few lines. I put the md5sum first on the line for sorting purposes. Right clicking on a folder and selecting Md5Hash should hash all files in that folder and subfolders. Again I put a sanity check value of 4095 so it is not designed for hashing every file on C:.
Here is the scenario how I automate using it to make sure all my downloads have not been tampered with. I use DownLoadThemAll to download all my zip files to a folder. I right click the folder and choose md5hash. Then I right click the folder on the HD that has my zip files for upload to my page. The "single instance" behavior adds the md5sum lines to the Edit Box of the already opened copy of md5hash.
After this I run a script that cuts the contents of the Edit Box to clipboard, reads it out, sorts it, and saves it to file writing 2 lines then a blank line until all the lines are written out. This file is then launched in a text editor. This makes it easy to see the files are sorted in pairs by md5sum. If there was any non match the whole pattern would be thrown off and it is obvious to the eye.
Anyway, if you have rather large files to process such as greater than 4 GB I optimized the file handling to work in large chunks. A 10 MB buffer is used so that even with multi GB files you can see the progress bar move along. Files can be added even though processing is running. They are added to a queue and processed in order with a count of the number of files remaining in the caption bar. I used a simple dialog type Win API application so that the program is a self contained exe. It should work on XP or newer English language Windows. You may download from my page here:
http://milesaheadsoftware.org/
btw it includes both 32 bit and 64 bit native C++ exe versions. If you unzip maintaining the subfolder structure running the context menu installer utility picks the one that matches your system. If I remember rightly it was compiled with MS VC++ 9.0 native 32 and 64 bit compilers with optimization set to speed.
I wrote this about 5 years ago. Other than the behavior I already criticized I guess the main drawback would be that it is md5 only. But for my purposes that was good enough. Even now, 5 years later, I see most download sites, if they only have one checksum to check your download against, the vast majority of the time it is md5. Not glamorous or the spiffiest UI but it is stable and solid.
