I'm currently using FileExists() to check for a file on a compact flash card through a USB reader. The card is formatted for FAT16. The product that uses the card now supports FAT32 so I formatted the card to that and can see and read the file through the reader. My call to FileExists() that works on the FAT16 card now returns UIEIOERROR (-93). Does FileExists() only support FAT16? Should I be using another function? I'm using CVI 8.5.1. Thanks.
