SanDisk iXpand Flash Drive 3.0

I key the correct password but receive a message “invalid parent path in archive”. I can’t access to the vault. Please help

Hi everyone,

Was wondering if anyone was using a USB flash drive with iPad Pro - haven’t been able to find a lot of material online about using them. I read a lot of PDF documents, and would like to be able to take documents from a computer onto the USB stick https://mobdro.bio/ and then plug the stick into the iPad to read them. Anyone doing similar? I may also work towards keeping iTunes movies on the stick to free up space on the iPad…is this possible? Last question, is it quicker on iPad Pros that have the USB 3 lightning connector?

Thanks!!
