Filenames saved to SD card with lower case extensions?

[DonaldMoran]

Hi liaminventions - Hope you don't mind me reaching out to you this way. I have been looking/working with the libfat32.a65 and libsd.a65 libraries from this repo, XPL-32. I am aware of the George Foot one as well as your fork, but ended here with these copies trying to come to understand why all files written to the SD card, regardless if the filename has an uppercase extension, are written as lowercase?

For example, if I name a file AAAAAAAAAAA, it is written to the card as AAAAAAAA.aaa ?

Like you, I have a home brew I have been playing with this against, and it's working well otherwise. I must admit though, it seems like I have stared at the code for hours and can not see where it modifies any part of the filename to become lower case, or upper for that matter :-)

I notice the George's repo, the same behavior with the creation of the TESTFILE.TXT, for me on my SD becomes TESTFILE.txt.

Is this true for you as well? If you get a chance and have some insight, I would appreciate you!

Also thanks for your hard work and sharing!

Regards,

Don

hey Don!
i've (as of a few days ago) actually come back to this project, and i've been fixing up the saving stuff in libfat32.
i also just saw this issue just now, so sorry about that.

to answer your question: i believe this is normal behavior. it currently it only supports 8.3 file extensions (same as in the george foot repo), and that must be how what OS you are using is interpreting the file name.

if i were to implement long file names (LFN), that would give us case control, although it's kinda unnecessary imo. (8.3 still works fine) but, it doesn't look all that hard to implement tho (probably will also do that)

also i'm interested: did you fix fat32_file_save yourself? the code's been broken for 2 years until now lol.
(mainly this bit was missing: 4445a05#r160943817)

i'm also interested by your project, do you have a page/repo for it?

also, i'm going to update my pull request to sdcard6502 once i fix the bugs in xpldos.

xpldos preview so far btw (fancy paths):
