MD5, SHA1 and SHA256 don't work on some MOV files

Hi Kim, David,

I am using Advanced Renamer 3.87, Windows 10 x64...

I am trying to write a script to sort photos and videos to uniquie but standardized folders and names as follows:

YYYY // YYYY-MM-YY // YYYY-MM-DD hh-mm-ss Country State City CamerMake CameraModel MD5[...hash...].EXT

The idea is to clean up doublets this way. All works pretty fine, but some MOV files have problems creating a MD5, SHA1 or SHA256 hash checksum.

I do get a "Ungültiger tag" error, which translates to "invalid tag" error.

// Add MD5 hash code to fileName
if ( app.parseTags( '<MD5>' ) ) {
// if ( item.md5Exists == true ) {
fileName = fileName + " MD5[" + app.parseTags( '<MD5>' ) + "]";
}

Unfortunately the error handling does not work at this point and I really don't see ANY reason why a file should not have a hash checksum at all?

I also tried using item.md5 but it seems to end in an error too.

I also tried adding the MD5, SHA1 and SHA256 tags using the GUI only, but the result is identical.

Is that a bug?
Any idea how to work around this?

Cheers
Axel

Hi Axel,
Just to be clear: Kim is the developer - I'm just an ordinary user who happens to enjoy solving other people's puzzles. It's a great way to polish up my JavaScript and regular expression skills!

David,

ok, thanks, good to know. You are VERY WELCOME in this case.

You seem to be a deep resource here in the forum!

Back to the topic, any idea on your side what is going on here?

Cheers,
Axel

I can't comment on the problem in ARen. However PowerShell has a utility for generating checksums - Get-FileHash so it would be worth trying this on one of your problem files to see whether it is a more general issue.

See: https://docs.microsoft.com/en-us/powershell/modu le/microsoft.powershell.utility/get-file hash

Simply type 'Get-FileHash into a PowerShell window and drag in a file to enter the full path. By default it will return a SHA256 hash but you can change the algorithm by appending "-Algorithm <type>".

eg Get-FileHash C:\path\filename -Algorithm MD5

Hi David,

I'll give it a try and will get back here soon.
Thanks for the idea.

Apparently the creation of the MD5 hash is possible without any issue on these files, see here:

PS C:\Users\Admin> Get-FileHash D:\Fotos\BatchMethods\TEST\Schattensprung.mov -Algorithm MD5

Algorithm Hash Path
--------- ---- ----
MD5 A0AB6F201412DDD06E6355EDB89114F1 D:\Fotos\BatchMethods\TEST\Sc...



It would not make sense for a hash function to fail on any file.

So this must be a bug.

At first I thought it may be a limitation in size, not to bulk process thousands of GBytes, which could freeze ARen quite a bit. But some MOVs of larger size work, while smaller ones don't.

Kim, any idea?
Do you need a sample file to track this down?

Cheers

Hi Kim,

In the meantime I found other files like .CR2 that don't work for hashing inside ARen.
I'd be happy to provide sample files if needed.

Please let me know.

Cheers
Axel

Has anyone an idea if I can run a DOS or PowerShell command within a script?
I might use external and working hash creation tools instead and revert back to the results I can get from these. But I am unsure if I can do this from within the script itself.

I want to skip any two-step renaming processes. The goal is to make ONE script that does the job of rename and moving files into a folder structure.

By using at least parts of hash codes within the names, I want to find doublets and filter them out.

Any help would be highly appreciated.
