I have same difficulty as OP and don’t see that the reply is helping .
I have new Sandisk Extreme Pro 128 GB and have copied onto this stick a number of folders with personal files which I intend to keep with me while travelling . Naturally , I want that info secure .
If I put stick into PC , all info is open to see on Windows Explorer . Any file can be opened without password .
Even if I have dragged a folder to the Vault area , same thing - folder can be opened and any file accessed .
At no point am I asked to insert a password except when running the exe file during set up .
I have tried reinstallation a few times , and only time I get asked to insert a password is during setup .
The user guide does not advise how to encrypt files , I just don’t get it .
Clearly the OP and myself are missing something “obvious” ?
Many thanks !
