Drives can be configured in many different formats. Most modern drives are configured in a format called NTFS, but some drives use a much older format called FAT32. Although the SecureBackup Desktop Software can be configured to store its cache on a FAT32 drive, it is recommended that you use an NTFS-formatted drive instead if possible. This is because the SecureBackup Desktop Software stores information about your files in a folder on your chosen cache drive, and FAT32 is limited to 15,000 files per folder. This means that if you put a lot of files on your SecureSync, or SecureBackup a large number of files with Backup, then the SecureBackup Desktop Software will stop syncing correctly.
When installing SecureBackup on your PC, the Desktop Software will try to select an NTFS drive to use by default. If you try to select a FAT32 drive instead, the installer will warn you.
Note that this will not affect the folders that you choose to backup with SecureBackup. If you want to backup files on a drive that’s formatted in FAT32 then you will experience no problems at all, as long as your SecureBackup cache is on an NTFS drive.
