I have a customer that is currently using a shopping cart which utilizes the file system as a database. He has one directory which contains thousands of small files (one per customer). In an effort to persuade him to move the system to a SQL server, can anyone offer me some numbers as to the limits on files in a directory? Are these OS dependent, or more specifically filesystem dependent? For instance, are there differant values for: msdos fat32 ntfs ext2 ext3 reiserfs v/r -Mike
