I develop under C3°° 1992 of Borland. Don't ask why. I know it, It runs faster than later version under Win/Dos and is perfectly compatible with Version 5.. but is easier to port around. Now I have a problem: the long file names. I tried a few parameter changes, etc.. I know there is a soure code of the functions fopen, mkdir, etc... I need where I could probably modify the size of the file name filed. Or is there another possibility. Thx for the help.
