[autocompiler]

Hello Guys here is the code,i am a newbie in autoit still learning so be patient whit me XD!!! i wanted to crypt the files inside user profile directory folders, in my case the music folder but even the picture or videos or documents,but it keeps giving me error also i wanted to do same thing for the decryption of the files please let me know what i am doing wrong!!

#include <File.au3>
#include <Crypt.au3>


$a_files = _FileListToArray(@UserProfileDir & "Music")

For $i = 1 To $a_files[0]
    $rc  = _Crypt_EncryptFile(@UserProfileDir & "Music" & $a_files[$i],@UserProfileDir & "Music" & $a_files[$i] & ".crypt", "APASSWORD", $CALG_AES_256)
    FileDelete ( "@UserProfileDir & "Music" & $a_files[$i]" )
Next

I still dont know if this script will encrypt only files or even the folders ? i wanted to encrypt everything  including the folders inside the folder music!! but also i want to be able to decrypt everything in it!!!And yes Music folder macro is not available if not the problem was solved i think!!!!

You'd be better off using folder permissions and native NTFS encryption in my opinion.  Folders dont get encrypted really, just their contents.  The folder is just a container.  At best you could rename/obfuscate it or "package" the folder into an encrypted archive, but then you won't have the flexibility to access to the individual files as easily.

Your FileDelete statement is malformed (syntax) by the way.  Take due care correcting it though if you're going to keep playing with the _Crypt_EncryptFile function.

Whole disk encryption like bitlocker is probably the best bet to protect a lot of files and still be able to use them regularly without a lot of time/trouble.

If you just want to block out a lot of files from access but then enable access to them later you can try NTFS but other administrators can change it, or if the disk is taken into a different OS or state that does not respect NTFS permissions it wont be protected.

Something like WinZip/WinRar/7Zip can add passwords to archives.  So you can automate packaging up the files into an archive with a password on it.  Pretty much would do exactly what you want to do, its just a lot of overhead depending on how much data your constantly packaging and then unpackaging.
