 joby_toss: I'm in love with this app! :)
Very useful and straightforward! [2009-11-30 19:30]

 AncientImages: I spent a day testing every integrity checker for windows, and this was by far the fastest. This program shaves a good ten seconds off the time it takes any other to calculate large (700mb+) files. You can even do batches. Very cool. [2009-11-30 23:01]

 Webfork: Does seem to run faster and better than many of the other hashing tools on the site. Works beautifully with entire directories. Another great Nirsoft freeware.

Its not hard to output the MD5 list to a file and compare them side by side, but hope the author integrates some kind of easy, automatic verification method in the future. [2009-12-22 15:03]

 joby_toss: @Webfork: I use "Options>Mark Identical Hashes" feature. [2009-12-22 15:51]

 CodesAway: Love this program!

I used to use Hasher (http://www.portablefreeware.com/?id=1347), but when it failed to compute the hash of a movie that I downloaded (~700 MB), I searched for a different program.

Not only can this program compute the hash for the movie, it's very fast, has TONS of useful options, and has awesome command-line support. I was able to easily integrate it as one of my "favorite tools" in FreeCommander (http://www.portablefreeware.com/?id=291), so now I can easily compute the hash for the selected files. [2010-01-03 04:14]

 Kermode: @joby_toss What does that even mean?
I want to generate hashes for a directory save it to a file. And then later compare the files against the hashes to make sure nothing has changed - this isn't possible.

Also, it colors the lines of the display without an explanation of what those colors mean.

I fail to see the usefulness of this app [2010-02-19 00:28]

"I want to generate hashes for a directory save it to a file. And then later compare the files against the hashes to make sure nothing has changed - this isn't possible."

If you want to ensure files remain the same, you can do just as you suggested. First, generate hashes for a directory and save it to a file. Second, at a later time, generate the hashes again and compare them with the previous hashes. If the hash is different, the file changed.

"Also, it colors the lines of the display without an explanation of what those colors mean."

The different colors mean that those files are identical (same color, same file) - it's useful to easily see which files are identical.

"I fail to see the usefulness of this app"

This program allows you to verify that a file hasn't changed. It's commonly used to check that a downloaded file wasn't corrupted when downloading.

Some sites have the MD5 hash for their program. After you download the file, you can compare the MD5 for the download against what the site says. If it's different, your download failed or was corrupted. [2010-06-28 00:06]

 John Smith: Best hasher I've seen. Drag and drop, copy and paste, or context menu interface. Great for bulk hashing. Copy a hash to the clipboard (from a website) and if it matches it will highlight green. Duplicate files highlight red. Just don't hit delete to remove files from the list. Use Clear all. [2010-08-01 16:28]

All HTML tags will be removed from your comment. URLs (http, https, ftp) will be automatically detected and hyperlinked. I reserve the right to delete irrelevant, frivolous or offensive comments. For more general topics (eg. whether apps that write to the registry, leave traces on the host machine, rely on certain versions of IE etc. can be considered portable), please post to the Portable Freeware Discussion forum. If your virus scanner has detected a virus in the application, please email the author directly or post to the forum. Note that false positives (i.e. flagging a virus when there is actually none) are extremely common for virus scanners. When in doubt, try an online scanner like Online Malware Scanner or VirusTotal, which scans files using multiple anti-virus engines. It is very likely to be a false positive if only a few engines raise the red flag.
