The prefix is added (randomly) to both long and short file names, so length of file name is not causing the issue. The original file name might have 4 characters, or 30, seems to make no difference.
Very few of the music file names on the USB contain a special character such as a (parenthesis), some have the prefix added and are unrecognised, some are fine.

Summary: my LG OLED55C7T TV adds a prefix to some file names on my music USB, these files then won’t play.
I want to play my music via a USB on my LG TV. I have copied my iTunes library from my iMac onto a USB. The USB is MS-DOS FAT32 formatted. (I have around 7,000 tracks on the 64gb USB, however I understand that the Player can only handle around 5,000)
The TV recognised the USB, and around 40% of the tracks will play successfully through the Music Player. These files names appear to be the same as those on the USB. However, the Music Player has added a prefix of ._ (period, underscore) to all the other file names and these files cannot be played with an error message “unrecognised file format”.
I cannot for the life of me work out why this prefix has been added to some files and not others. I have established that the problem is not caused by Apple MPEG-4 files, nor by AIFF-C audio files. It does not seem to make a difference whether my original file name starts with a letter (either lowercase or capital) or with a numeral, the adding of the prefix appears random to me at this stage. Some files names include a hyphen and will play just fine.
With 5,000—7,000 tracks, manually changing the files names on the USB is not an option, particularly because I can’t determine what is causing the issue. (I did try a few options!)
I have contacted LG support, however at this stage, they have offered very little.
I’m not a tech nor audio head, and am only familiar with Apple products. So advice in really simple layman terms would be appreciated.
Many thanks
