[feature] Allow to enforce case insensitive filenames

[digimbyte]

⚠️ This issue respects the following points: ⚠️

• This is a bug, not a question or a configuration/webserver/proxy issue.
• This issue is not already reported on Github OR Nextcloud Community Forum (I've searched it).
• Nextcloud Server is up to date. See Maintenance and Release Schedule for supported versions.
• I agree to follow Nextcloud's Code of Conduct.

Bug description

due to a case sensitivity on the server, it'll accept one version over another, soft locking the desktop from downloading or merging the files.
example: Misc vs MISC
both can co exist in the server rather than being merged or aggregated

Steps to reproduce

1. client A creates a folder with an upper case name
2. client B creates a folder with a camel case name
3. desktop app will only download one due to OS restrictions, some file merging may be present but files will not be visible to the desktop client
   

Expected behavior

folders will merge, OR at least warn the desktop client that folder names are duplicated and should be resolved, throwing an error.
would like an aggregation function on the server

I tried renaming folders locally but it causes the desktop app to crash on sync

This is current expected behavior. Nextcloud will handle case insensitivity if the storage used does not support it (e.g. external samba storage).

[digimbyte]

it's actually causing crashes on the desktop client so.. No, it's not "working" for us as we use the system to develop and share production assets. we were missing 2.4gb of content due to this 'feature'. it's not optimal or user friendly no matter which way you slice it. I've had to uninstall the desktop and aggregate files manually to merge them because it causes an instant crash on the desktop client.

Then it seems to be a Desktop Client bug, you can report here:
https://github.com/nextcloud/desktop/issues

Maybe it is related to this report here:
nextcloud/desktop#6011

You can also enable case sensitivity for the sync folders on your windows system:

Can we instead enable case insensativity on the server side as a feature or setting?
And no, I cannot enable case sensative names as it's local drives only, not external media.

I do need to now hunt down all similar folder names on the server and rename them all. This seems daunting as we have over 50gb of resources uploaded by multiple clients.

Could be a feature request

This is currently not possible, but is a planned feature for Nextcloud 30.

Currently case insensitivity checks are only performed if the external Nextcloud storage does not support this (e.g. some Samba configurations).
