Comments on: exf command line usage http://www.exactfile.com Making sure that what you hash is what you get.

Many thanks. BUT I only need CRC32 and cannot generate the relevant SFV checksum file. I've tried nearly all combinations of your options -- but in vain. I simply have a folder (say, C:\My Folder) for which I want to generate a CRC32 checksum file recursively stepping through all subdirectories, then, after copying the folder with the newly created checksum to the external HD folder (say, H:\My Folder), to check the copied checksum against the copied folder files. Your example works well for -md5sum but I can't break it down into its component parts in a way that works and that I can then 'convert' to CRC. Can you please help?

It only creates a file if there is one missing, the hash file is not the most recent in the directory, the directory has been modified or if the count of items in the hash file does not match the number of files in the directory. Once I've done some more testing I'll post the code publically. In testing I've found that the command line and app finish the file differently. The app finishes with the number of files hashed, whereas the commandline doesn't. If the command line had the number of files, checking would be better.

Put that in a FOR loop and you can easy move the files... @rudis
Found the basic part my self! :)

(for /F “usebackq delims=” %i IN (`dir /s /b *Arome*.sfv`) DO @(@exf -c %~fi | find /I “No errors”) && @echo %~fi) | FIND /I /V “No error”
This command pick out all sfv-files that are ok!
Put that in a FOR loop and you can easy move the files…

With this command i liked it to print "0" if all is ok? for /F "delims=" %i IN ('dir /s /b **.sfv') DO @exf -c "%~fi" | @echo %errorlevel% Goal is to move complete/checked folders to another directory... Great tool by the way, using this and md5deep/hashdeep Does the exf send eny error codes?

With this command i liked it to print “0″ if all is ok?
for /F “delims=” %i IN (‘dir /s /b **.sfv’) DO @exf -c “%~fi” | @echo %errorlevel%

Goal is to move complete/checked folders to another directory…
Great tool by the way, using this and md5deep/hashdeep
