Zotero 8 not renaming attachments

EnfantNicolas · 2026-01-26T11:28:52+00:00

Good morning all,

There seems to be a problem with the automatic renaming of attachments, as the feature stopped working this morning: all new attachments are keeping their original file name instead.

Of course, the settings are as usual.

Any ideas as to why it's not working as intented?
Many thanks,

How did you add those? Can you provide steps to reproduce this with a newly added item?

Also, your screenshot shows attachment titles. Can you show the attachment item pane, which lists the filenames as well?

Steps to reproduce:

1. Start Zotero.
2. Find whatever article we want to add the file to
3. Find the file in file explorer
4. Drag and drop the file into the corresponding article entry

What i expect to see: file gets added and attachment title gets changed to "PDF", while file gets renamed according to filename format.

What happens now: file gets added but both the attachment title and file name stay the same, which is to say identical to the original file name.

When the item has no other attachments? The behavior you describe is correct if there's already an attachment on the item, but it shouldn't do that for the first attachment.

If you're seeing this for the first attachment, can you reproduce it in Troubleshooting Mode (Help → "Restart in Troubleshooting Mode…”), which temporarily disables all plugins?

Here is the procedure in Troubleshooting Mode, it is the first attachment ofc. :

Ah, OK, this is in a group library. That's a bug. We don't currently expose a custom filename format in group libraries, but it should still rename and retitle properly. We'll fix. Thanks.
