Ken,

VFP array before VFP9 are limited to 65,000 items which comes to 13,000 rows for ADIR. You can use SYS(2000) to loop through the files in a directory.
Anyway, it's not a good idea to store so many files in one directory because it could slow down file access. You should condider to split them into subdirectories.
