HashTab - Great little tool ...
« on: January 10, 2009, 05:43:11 AM »
I started using this years ago but just found out there is a new version available.

Basically it adds an extra tab in file properties in Windows Explorer and calculates the hash check values for the files. Currently it supports up to 12 different hash calculations (you can select which ones you want to actually calculate).

For example:

HashCheck Shell Extension does that too (and is much smaller in size). It is for both 32-bit and x64 Windows.

Quote
HashCheck can process and verify the checksums/hashes stored in checksum files--these are files with a .sfv, .md4, .md5, or .sha1 file extension. Just double-click on the checksum file, and HashCheck will check the actual checksums of the listed files against those specified in the checksum file.

HashCheck will add a "Checksums" tab to the shell's file properties dialog so that you could easily check the hash of a file (or even multiple files and directories) from Windows Explorer. You can also save the results to a checksum file.

HashCheck adds an optional "Create Checksum File" command to the shell's context menu.

Wow, also nice!  I like the checksumming of folder-content feature.

Mmm, source code :)

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:
    Quote
    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.
    (A very handy feature.)

I don't know about the other checksums, but a nice feature of the MD5 Hash algorithm is that it is designed to produce wildly different strings on the smallest difference.  It eliminates the need to do side by side string comparison.  If I do an MD5 Hash to compare files I just look at the first 4 characters in the string.  I've never seen an instance where they match and the rest of the strings do not.

Anyway, to pimp my own version MD5Hash is available here.  It queues up files to a depth of 4095.  You can right click a fairly large folder and let it go.  I tried a hybrid single/multi-instance scheme, but it is quirky since window creation, which is the governing resource of single instance, takes to long to guaraantee only one instance.  But if a copy is already open, multiple right click in Explorer sends the command lines to the open copy.

Unfortunately I don't have the source anymore to de-quirk it.  :)

Thanks for taking a look.  It's a vanilla c++ dialog.  It's main feature, other than speed, is you can feed it multi-GB files and it won't choke.

I just thought I'd mention, on Windows 8 MD5Hash dialog may look grayed out and the edit control with the hash results hard to read.  This is due to MS changing how Glass and composition works from Windows Seven.

Unfortunately I have no practical means to fix it. Sorry.

A work around is hit control a in the edit control to select everything and/or copy to clipboard.

Thanks for the report.  I have been using a Glass customization tool for W8.  Not as nice as W7.  But it looks pretty good when used with Aero Glass Tweaker, if the included resource file is used.  In that case the dialog looks sort of like clear plastic.  But the sums can be read easily.  If interested it's Aero Glass for DWM by Big Muscle.  :)  Links for the files can be found in threads on the Windows8 Customization sub-forum.
