FS#8174 - path length of >= 256 bytes is problematic?

(This is on a Nano 1st Gen)

I have a specific filename that rockbox cannot open. The same file, in any other directory, or with any other name, is openable; any arbitrary file with this name cannot be played or “Properties”ed.

The path that fails is

Rockbox can display the file in the browser (the œ is displayed as the “no glyph” character, whatever).

I discovered this is not a unicode thing (All the other files in the same dir have the same œ; plus the same non-functioning file works if e.g. copied to the root directory)

This seems to be a maximum length thing. Neither this file nor the one that is 5 characters longer (256 and 261 unicode entities long) can be played.

This may be related to the maximum of 255 ucs2 entities for a filename (not path!) on VFAT.

(I probably should use shorter filenames, but…)

Thank you very much for an awesome piece of software!

use shorter filenames…

Project Manager

According to the FAT32 specification, the maximum length of a complete path (including the filename) is 255 characters. In your case, the path including the filename is 256 characters.

Could we get a little warning regarding the problem when the user tries to select a path name that’s too long? It took a while to figure this out, when the only symptoms were “I can’t play it”.

(Looking up the standard, microsoft seems to say “260 bytes, including the [driveletter]:\[nul]”, which is a max of 256, not 255, but that’s just being pedantic)
