Omega2+ treats files as dirs on USB drive. Why?

Pavel Negrobov

Hi guys.
I have a USB flash with files with russian names. This is from windows:

24.04.2020  14:22        39 576 966 женщина.bmp
24.10.2020  19:56         6 912 054 winpe.bmp
22.01.2021  19:30         3 448 960 Vis - Песня_про_нечисть.mp3
28.01.2021  15:03           165 623 tela_tst.psd
07.03.2020  19:03           205 406 pacan_mini_layers.psd
17.11.2020  12:53           231 080 angelsmal.bmp
13.06.2021  09:16    <DIR>          В_Цой
13.06.2021  09:16    <DIR>          Dir1
13.06.2021  09:16    <DIR>          asdf

Note that женщина.bmp is file.
Same USB flash in omega2:

drwxr-xr-x    0 root     root      39576966 Apr 24  2020 женщина.bmp
root@Omega-3079:~# cd /mnt/sda1/женщина.bmp
root@Omega-3079:/mnt/sda1/женщина.bmp#
root@Omega-3079:/mnt/sda1/женщина.bmp# ls -l
root@Omega-3079:/mnt/sda1/женщина.bmp#
root@Omega-3079:~# cat /mnt/sda1/женщина.bmp
cat: read error: Is a directory

As you can see 'женщина.bmp' - directory, not a file!
Why? How to avoid this?

Pavel Negrobov

Some experiments show that this bug present only on FAT32 disks.
On exFAT and NTFS all good - женщина.bmp -- file, not a directory.

Mounting USB drive with shortname=mixed option fixes this bug

/bin/mount -o codepage=1251,iocharset=utf8,shortname=mixed /dev/sda1 /mnt/sda1

Problem solved.

@Pavel-Negrobov If you have the time it might be good to log a defect on openwrt.org, if nothing else it would help others using Russian.

Pavel Negrobov

@crispyoz I will do this later when I will finish my python soft, I need to check chdir to russian named dirs and read files.

I have two external drives and I'm hoping to make finding what I have and where, by topic, much easier than "plug in and hope I'm right". Is there an easy way to do this? I'd love to scrape the file and folder list of a drive and then I suppose tag folders or subfolders by relevant subject and possibly even by importance (obviously that I'd determine) and be able to see what is where on my computer without needing to physically access a drive to be sure. I'm not sure if this is at all possible, though.
