Freeware Rebooted

I like "HashMyFiles" from Nirsoft.


It is portable,

I can drag/drop multiple files into it and it shows simultaneously the MD5, SHA1, CRC32 checksums,

plus sundry details such as file name and path, size, timestamps etc.

Each file has a row, with details in columns allowing instant recognition of whether files have perfectly matching checksums.

Alan, can you explain to me more about the purpose of a hasher?


Correct me if I am wrong. It seems this must be used for every file you intend to use, then updated for the updates, which seems very time consuming to me to tediously hash, check hashes, etc. when you have multiple thousands of files to test?


I wonder what you use it for mostly? I may would, but I just can't see wasting that much time for what I do on here. I presume its a specialized thing for users planning to have around 50 or fewer files to hash?


Please enlighten me as I have heard many people speak of hashes & I wondered what their significance possibly could be unless they are applied to every file & every updated version of that file... Which would seem a waste of time to me.


But I may be wrong. I truly would love a more detailed explanation so I can make a more well informed choice.

Looks interesting. I've always used WinMd5sum to check file hashes, always done the job for me.


MD5 is now considered in-secure. Yet I still mostly see it listed on websites.



Here's another one (HashCheck)


That looks more inticing than the one I just started using, the small size and ability to use checksum files all from one program will be nice.

Don't want to steal Alan's thunder here, just want to add a vote for Nirsoft's HashMyFiles. Its fast.

It is a standalone exe, just store it somewhere and click it when you want to use it. It opens a window.

You can drag into it's window a single file, a folder, a zip file, or an ISO file, I've done all those.

It puts the results for each file on its own line in its window.

If the hashes of two files match, the lines for them will be the same color.

That makes it fast ... if one out of 20 lines in the (Hasher) window is NOT colored, that file alone does not have a match.

One small additional feature is that you can highlight multiple files simultaneously, right-click for Properites, then the checksums for all of those files are displayed in the Checksum tab.

My primary purpose was to validate a download of any "important" file.

It is rare, but I have experienced a successful download which failed hash checksum validation,

even though the download passed the Internet Protocol tests that determined whether a packet needed to be re-tried.


The hash checksum is as provided by the developers - if they are bothered or pressured by users.


From the trusted supplier site the checksum can be copy/pasted into notepad and the download can be obtained.

Sometimes the checksum Hexadecimal values are stated in Upper case, sometimes in Lower case.

HashMyFiles can compute the hash checksums and can select whether to display the Hexadecimal values in Upper case or lower case,

and the relevant MD5 or SHA1 value can then be pasted into Notepad on the next line for immediate comparison.


If Piriform published hash checksums for their products,

it would be possible for Download.com to also publish a checksum for their spyware variant,

and to justify that action on the basis that it was needed to validate the accuracy of the Internet transfer.


I actually doubt the NEED for using hash checksum validation on CCleaner BECAUSE

Its properties includes Digital Signatures and by selecting the name of the signer (Piriform) and clicking "Details" button,

it will think for a very much longer than HashMyFiles would but eveyually it tells me

"This Digital Signature is OK."

By clicking on "Advanced" I see

"Digest Algorithm sha1"


I need HashMyFiles for speed even when there are Digital Signatures,

and often software does not have Digital signatures built in.

@ Super,

I use HashMyFiles to compare files. It ignores file names.


For example, ccsetup321-1767.exe is a renamed copy of ccsetup321.exe ... same hashes.

The "PDFXVwer.exe" files are different versions w/ same name ... different hashes.

The WindowsXP-KB936929 ... exes are the same file from 2 different folders, different download times ... same hashes

Guess I could delete one of those. :P

Valuable app for an incorrigible downloadaholic with a poor memory.

I also have used Nirsoft's HashMyFiles in the past, it's how I was able to get rid of hundreds of duplicate files. However nowadays I need the ability to create checksum files which I can store on a data DVD to scan the whole disc for matching hashes to know if there's any disc errors years into the future.


One small additional feature is that you can highlight multiple files simultaneously, right-click for Properites, then the checksums for all of those files are displayed in the Checksum tab.


I tried it out and liked it initially however I don't know if I found a bug in HashCheck, or a Windows issue/limitation using it.


When making a checksum file for a whole folder structure with sub-folders and saving the checksum file directly into that folder it will display a "mismatch" error for the .SFV, .MD5, .SHA1 checksum file itself which should not have a computed hash on it to begin with. It's definately not what I expected as it should be able to ignore such checksum files it's in the process of creating like some other recursive hash tools do.

What I like about it:

Very low system resource usage, even on old XP systems with limited RAM. It's really easy to use and has a bunch of profiles to support many devices and hardware. Also unlike many other video conversion tools when you tell it to output a video to DVD Video it does just that by creating a burnable DVD Video folder instead of some bog standard .MPG file.

All these are freeware and still in active development. I leave it to you to discover what these do. I'm too lazy to type a description. But rest assured, this is all quality stuff that's been around for years and years. And there's no spam or toolbars or any annoyances with these. Nor are the web pages gonna do a driveby on ya' either..

Probably, I'd need to research further. There always seems to be some sort of licensing agreement dispute when it comes to codecs and media. It's like the same thing with PhotoRecovery software. Utilities could be made better if they could get around (or pay) the licensing fees for permission to write certain headers. Ugh..

Nice little tool that monitors harddisk activity. And when the computer accesses the harddisk then the DiskLed system tray icon lights up. When my laptop (Win 7) goes through the start up procedure (e.g. MS Security Essentials) then for the first 1 or 2 (3 ??) minutes this system tray icon constantly lights up revealing constant disk access/heavy disk usage.


When the icon no longer constantly is lit then I know that my computer is completely at my disposal and will start to respond (almost) instantly to mouseclicks.





For the time being, this is the best and - above all - simplest diskmonitoring tool I came across.

Yes, but that light is located on the side of my laptop and therefore it isn't visible when I use my computer.


Well that doesn't seem helpful at all.



Unrelated: I've been enjoying this freebie: http://pnggauntlet.com/ "PNGGauntlet"


It recompresses JPG, GIF, etc as PNG if the conversion will make the file smaller, and it recompresses PNG files to make them smaller. I've seen compressions as high as 14% the original size, but it seems average around 70-80% original size.


A note though: If it compresses a non-PNG into a PNG, it leaves the original file
