After two days of trying many many free and paid software solutions I am finding that there is a real problem in usability and portability of encrypted data on USB drives. The goal is to provide a seamless, easy way for users to simply drag and drop their files.
Every solution I have come across so far either requires an administrator to install the file system level drivers or leaves the data un-encrypted until it is specifically selected and encrypted. Neither of these solutions will work as I know my users and when they bring their PowerPoint slides to remote locations they will not have administrator access and relying on them to manually select and encrypt/decrypt files is simply not going to happen.
Are there any solutions where a user can simply plug in the USB drive, put in their password, and drag and drop encrypted files?
