Clean-up operation moves files from file-field to pdf-field and can afterwards no longer be opened directly from JabRef.

[apacha]

When I'm cleaning up an entry, the linked PDF is moved from the file={} field to the pdf={} field. Afterwards, it can no longer be opened directly from JabRef:

JabRef version 4.3.1 on Windows 10

Steps to reproduce:

1. Create entry

2. Link file

3. Clean up entry

4. Icon to open file from JabRef is gone (the small icon in the table view).

Oh. Found the solution - "Upgrade external files to use the file field".

Just out of curiosity, a normal cleanup should not move the file from the file field to the pdf field - even if you don't check the box. It could be a potential bug you have discovered, but I am not sure.
I see you have the convert to bibtex enabled. @koppor Do you know if the bibtex conversion does this or if this is intended?

Just discovered an additional (potential) bug, that is related to this: When cleaning up multiple files with the "Convert to BibTex" option enabled, only the first selected item gets converted, instead of all selected items.

@apacha Could you copy and paste the bibtex entry here as comment? Use three backticks before and after to make it even more easier to follow.

@Siedlerchr I have no clue and it should not happen, because we got rid of the PDF field looong time ago. - Refs #251 and probably #98, #1052 and #865

@koppor here you go. It's nothing special.

Okay, I could reproduce this with the convert to bibtex cleanup. Definitively a bug
