SanDiskSecure Access puts all the files for a vault into a single directory regardless of the directory structure it shows on screen. This can be seen by using File Explorer.
If using FAT32 when you try to put over 13,000 files into a SanDisk Access vault you will get this error.
Possible solution upgrade to a newer file structure (eg exFAT, NTFS) Create multiple SanDisk Access vaults does not work as the file limit applies across vaults.
