folder creation is not relevant for ownCloud, it's not used anywhere.

does the modification time change ?

I'm not aware of any process that would touch the date/times of folders directly on disk. The scanner is not supposed to touch the storage in general.

Dear @PVince81

The modification occurs in the database, the files and folders on the hard disk remain intact. In the desktop client nothing is modified at all.

The modification appears in the web version of owncloud and in the client for Android that I use, I fear that it will also happen in the other cell phone clients.

Yes it is relevant because all folders appear in such clients as recently created and it is impossible to sort by date to quickly access the last created, which is a function that I use often and I think many users.

If this is not relevant to the developers of ownloud, I am sorry to read it and I hope it is a misinterpretation. I repeat that for me as a user it is a relevant problem.

I would like to inform you that I found the inelegant solution in this link that refers to Nextcloud:

nextcloud/server#1583

Basically by accessing the database and executing the query:

UPDATE oc_filecache SET mtime=storage_mtime

I would expect a more elegant solution from the owncloud developers

[PVince81]

ok, so it's not creation date but mtime of folders.

I don't think the scanner is supposed to touch these mtimes in the database so would consider it a bug.

Ok, it is the creation date of the folders that are changed. mtimes of folders make them look that way in the web and mobile version.
