Can not add any more to Sandisk Ultra 3.0, although only 35% full

I apologize if there is already a thread about this, I couldn’t find it.

Sandisk Ultra 3.0 64GB - SanDisk SecureAccess V2.0

“Can not open file for write E:\SandiskSecureAccessVault…The directory or file cannot be created.”

If I delete a few things, I can add more. I read in onther thread to format it to ‘exFAT’, but it is the default. Other choice is ‘NTFS’.

USB Flash Drive, Vault Protection: AES128

20GB of 57GB used (35% full)

Have you heard of this?


Please try to format the drive one more time to ExFat and after that try to see if the vault is again receiving this error message .
