I see in wiki for AVR-dos :
• Short file name (8.3)
• Files with a long file name can be accessed by their short file name alias

my question :

I need the same id_number for 2 files the fist is for exemple : 12345678P.TXT the second 12345678S.TXT

the id_number change all time, it is send to me by user but always with 8numbers and 1 letter
so how could i use alias ?

you can simply test that.
create 2 files and then check with DIR /X :

123456~1.TXT 12345678P.TXT
123456~2.TXT 12345678S.TXT

Thus 123456~1.TXT is the short for 12345678P.TXT

I did not test what happens if you copy the files to a different PC and if the long info get lost. i guess so since the long name is stored in a table. it depends on the kind of FAT. FAT32 probably saves this info.
I say probably since i did not look longer into it than 1 minute.

it is much better to use a naming method yourself.
