Description Roke Julian Lockhart Beedell 2024-06-10 12:02:03 UTC 
SUMMARY
As https://invent.kde.org/system/dolphin/-/merge_requests/695#note_965019 explains, I do not see a warning when renaming, such that it shall be hidden when renamed, a file or directory (I've not tried other filesystem objects, like symbolic and hard links) although, as https://invent.kde.org/system/dolphin/-/merge_requests/695#note_965313 demonstrates, it should.

STEPS TO REPRODUCE

1.  Create a file containing a period at the start of its name.
2.  Observe the warning, as https://invent.kde.org/system/dolphin/uploads/f2dadd0e5554177ba49c3f99ba892251/Screenshot_20240609_195931.png demonstrates.

3.  Create a file containing mere letters as its name.
4.  Rename it such that a period is at the start of the name, as https://invent.kde.org/system/dolphin/uploads/c8db2b2be1d678801210963bb1b01c08/Screenshot_20240609_200132.png demonstrates.

OBSERVED RESULT
The warning solely appears during creation, not renaming.

EXPECTED RESULT
The warning should appear in both instances.

Inline file rename with warning present, except for `.old` file extension.

When using inline rename, you get a warning when adding a period to the start of the name, but not if you add .old extension.

(In reply to Linus Kardell from comment #5)
linus.kardell@gmail.com, that's a good catch. I'll expand the scope in the title to encompass that too. Do you know whether any other file extensions exhibit that behaviour? I recall an Invent thread where a few more equivalent extensions were mentioned.
Comment 7 Linus Kardell 2024-06-10 18:49:06 UTC 
It's the application/x-trash mime-type, which is used for files ending in .old, .bak or %.

It's the same when creating files BTW, you get a warning if put a period at the start, but not if you add an application/x-trash extension.
