You can use Flat View to get the MD5s of multiple files, but the Clipboard COPYNAMES command won't include the path for the files; just the names.
You could turn on the checksum and location columns and use the Print Folder function, sending the results to the clipboard or a text file, but that wouldn't match the output format you've got there.
If you want the same format it's probably easiest to use QuickSFV or a similar tool. You can create a button to launch/automate it from Opus, of course.
Sorry, didn't realise that QuickSFV lacked a command-line interface. There are plenty of other MD5 tools that have command-line interfaces which you could use instead though.
I think I have tried them all! I have not found a single MD5 tool that can recursively go through the subfolders (except QuickSFV). If you know one, it would be of great help.
Here's one I wrote a few years ago which does recursive output. It doesn't put the * before each file path, but other than that I think you can make it do that output. csmd5.zip (30.3 KB)
Thanks. I just tried it. This is a nice too. I don't know if you are still developing it or not but with minor changes it would be very useful. First if it outputs *, it would be standard and readable by other md5 verifying programs.
one other issue is that it calculates the md5 of the output log file also which it shouldn't.
