And can you please clarify the license. If I have a one user/pc license and need to install Cloudberry on another pc temporarily, would I need another license?

Matt, please understand that when I travel I probably would not be able to install Cloudberry locally: not my system/s; not my security protocols. So it's not rare, and would apply to any other similar software I might use, eg ARQ. An external HDD or USB is not relevant until/unless the data can be decrypted.

It's a problem, and as yet I don't have a solution.

In many situations, it is not possible to install software onto a local machine due to security restrictions, so the answer to my first question appears to be that I CANNOT DECRYPT MY FILES"!!

Do you agree?

Thank you for the very speed response. But what if I can't install the software due to local restrictions? Very common in commercial situations and indeed in hotels.
