Create simultaneus Checksum File

Post by *Impeeza »

Hi, I recently start to use huge files for backup; sometimes I need to create MD5 and SHA256 checksum files, by now I have to run the process:
"Create Checksum File(s) /CRC32, MDE5, SHA1)..." twice, but with files 32 GB or more on size the process take so long.

There is any way of generating both checksum files at same time?

This is currently not possible with TC. But Hashdeep (Download at GitHub) can help with that, that is if you're not afraid to use command line tools. However, I'm not sure if the checksum file format written by hashdeep can be changed since it's not the same as in TC and other programs.

I've had the necessity to create multiple different checksum types as well, so I support this suggestion!

Possible with an external tool like FSUM by SlavaSoft.

For each selected file do create an separate checksum file:

Output: OrigName.ext _CheckSum.MD5
GC '%WF'|ForEach{&"""$($env:Commander_Path)\Tools\fsum.exe""" '-jnc' $_ > """$_ _CheckSum.MD5"""}


Output: ___CheckSum_OrigName.ext.MD5
GC '%WF'|ForEach{&"""$($env:Commander_Path)\Tools\fsum.exe""" '-jnc' $_ > ('___CheckSum_'+"""$_"""+'.MD5')}

Code: Select all

GC '%WF'|ForEach{ & """$($env:Commander_Path)\Tools\fsum.exe""" '-jnc' $_ > ('___CheckSum_'+"""$_"""+'.MD5')}
Test|PowerShell|Get Hash for each selected file


GC is "Get-Content"

For use with TC we have to escape the "..." quoting by triple them to """...""".
Or use single '...' quotes if you don't need to expand $vars.
