I am working in an environment where people share the same PC running Windows 7. I would like to put my private files in an encrypted partition so that I can lock it when I leave the PC, yet leave the system available for someone else do use (physical access) and unlock it when I return without rebooting the entire system.
We do not have a file server available. Our version of Windows does not have BitLocker installed.
Is this possible using preferably a free software?
