[yorukot]

What does the metadata panel show before press up?

[TypicalAM]

Nothing:

I'm going to try to fix this, but I don't have a file without metadata. It's a bit difficult to test.

If you don't mind, could you send me the file or tell me how to get it?

[TypicalAM]

Here it is in docker, can't really tell anything more:

• docker run --rm -it golang:1.23-bookworm
• go install github.com/yorukot/superfile@latest
• cd $(mktemp -d) # Creates a temporary empty dir and enters it
• superfile # m and up

Ok thank you so much!
