Checksum Options

Postby shhac » Wed Sep 12, 2007 2:15 pm

The ability to add the files checksum (e.g. CRC32 or MD5) in the file name, just before the file extention would be pretty useful for me.
Especially if there was the options for things like "normal/square brackets around checksum" or "(no) space proceeding checksum", or a "replace file name completely (includung/excluding file extention)".

I understand that these types of options would require a lot more processing time to do than the currently avalible ones (so it should only be calculated when its used, not for everything), and depedning on the language BRU is written in, providing these features may require alot of coding, but this is the suggestions category so I thought I'd share the idea anyway.

Yes, a checksum renaming option would be nice (if it is possible also for the command line version). It seems that an other renaming tool named PFrank (http://www3.telus.net/pfrank/) can rename files based on their checksums.

Just for my own understanding, why would this be a useful feature? I've only ever used checksums occasionally, to verify large .ISO downloads, and even then the checksum is normally in a separate file.

I'm not dismissing the requests, I just can't see why anyone would want to put a checksum in the filename.

Cheers,

But it may be useful if you for example collect and store files and you want to have also the checksum in the filename. Ok i know this sounds strange and the renamed files probably look not really nice with a checksum in their names, but for users that just need increasing count numbers and/or checksum in their filenames it is enough. It is not really a must have (as i think), but it would be a nice feature :roll:

i just wrote a script so i can rename files by their md5 checksum

set /p directory=
FOR /R %directory% %%a IN (*.jpg) DO (for /f "skip=3" %%b in ('fciv.exe "%%a"') do rename "%%a" "00%%b%%~xa" || if exist "00%%b%%~xa" delete "%%a")



you have to download the FCIV.exe file here: http://support.microsoft.com/kb/841290


also.. it would be great to have this functionality in BRU. It's pretty much the ultimate way to differentiate a large number of files.
