locked parent directory after show file with japanese chars

[RM8MR]

If I open file with japanese chars in name, parent directory is locked and cannot be renamed.

I create two directories (F7): "Dir1/Dir2".
I create empty file "ここに.txt" in "Dir2" (SHIFT+F4).
I show the empty file (F3) and press ESC to close.
Now, If I want to rename "Dir1" it will show error dialog (Please remove the write protection).
NOTE: "Dir2" is not locked and it can be renamed.


This problem is in TC10, TC11b9

Not confirmed. My guess is that a Lister plugin tries and fails to open the file.
Does the same problem happen when you press Alt+Shift+F3 to view the file, and then ESC to close?
This will open Lister without any plugins.

If it doesn't happen with Alt+Shift+F3, you can try switching manually to various plugins until the dir is locked.

Confirmed and confirmed for older versions as well (oldest tested: TC 7.50a).
Renaming in Explorer fails too.
Closing TC solves the problem.

Did you read my reply? Could you try with Alt+Shift+F3?

[white]

Yes, tried it. Same result. I tested without plugins anyway.
Did you try to rename the correct folder, Dir1?

[ghisler(Author)]

Doesn't happen here. Could you install lock hunter to find out whether the file itself is locked, or one of the directories?

[white]

On my hard drive C: it works OK. On my hard drive D: it doesn't work OK.

[RM8MR]

I can confirm what white says.

- Alt+Shift+F3 - do not work
- on C drive it works

Lock Hunter:
Dir1: Locking Processes : TOTALCMD64.EXE
Dir2: No process locking this file or folder have been found
ここに.txt: No process locking this file or folder have been found

I can confirm that it happens on drive D: but not on drive C:, very strange.

[RM8MR]

I think the problem is that folder names are not in japanese.
If I do not create "Dir1/Dir2", but I create folders "きけ/なに", I can show file "ここに.txt" and then I can rename first folder "きけ".
Now it works.

[RM8MR]

Sorry. It do not work if I use japanese chars in folder name.

If I use japanese chars in folder, it still lock second folder without japanese chars.
In this path is locked "DirA":
d:\ TMP \ DirA \ DirB \ きけ \ なに \ ここに.txt

Confirmed. Probably this is the case for any unicode character. I tried it with: d:\TEST\DirA\DirB\\.txt

[ghisler(Author)]

I found the reason: It happens when a drive doesn't provide the alternate DOS file names in 8.3 format (8 name, 3 extension) for Unicode file names from a different code page. Lister tries to get them for plugins which don't support Unicode. The directory handle isn't closed in case of error (no name found).

03.07.23 Fixed: Lister: Viewing a file where the name contained Unicode characters from a different code page would keep the directory locked if the drive didn't support alternative 8.3 DOS names (32/64)

Tested OK using TC 11.00b10 32-bit and 64-bit.
