If that’s the case, AxCrypt is not the droid you’re looking for. AxCrypt is a file encryption software, which means it encrypts single files, file by file. This has advantages and disadvantages depending on your scenario. If you are primarily interested in keeping your PC secure for the scenario where you lose it or it get’s stolen, I recommend Bitlocker to encrypt the entire hard disk or volume.
The other alternative is to use a volume encryption software such as VeraCrypt.
AxCrypt is more suitable to protect data that actually leaves your PC, for example via email or a cloud storage provider such as Dropbox, Google Drive or OneDrive etc.
