You can achieve the same in the AxCrypt app.
You can encrypt the folder/file(S) using AxCrypt Secured folder features.
AxCrypt secures files, individually. However, you can designate folders as ‘secured’. The folders will be monitored for new files, and AxCrypt will secure all new files with a single click, or when you sign out.
You can also select multiple files, including all files in a folder, to be secured in a single operation. They still remain individual files, and the folder itself is not secured, just the files in it.
AxCrypt is only limited by available hard disk space. If you have enough space, then you can encrypt the full drive. When encrypting bulk amount of files or larger files, AxCrypt will take some more time to finish the encryption/decryption. AxCrypt performs as much as faster based on the user’s system configuration and the file size.
We do have a some performance issues(when work with more than 10000 files) and we are working on the application improvement.
