OK, so I'm a bit of a tech-dummy.
Here are some questions:
1) If I install Boxcryptor on PC1 and then encrypt a Dropbox file on PC1, what will it look like on PC2 (without Boxcryptor installed), will I be able to see this file at all?
2) Does Boxcryptor require space for a complete mirror of my Dropbox size?
3) Is it safer to encrypt a file first then upload it to Dropbox, and if so, is it possible to do this with Boxcryptor?
