When you copy or move an encrypted file to an unencrypted folder, the file is still encrypted.
If you have enabled a folder to encrypt files and you move or copy an unencrypted file to it, across partitions, it will become encrypted at that point.
here's the link.

i tried to do some exercises about this but somethings not going right as stated.
1. i made a folder and i encrypted it and i tick
apply changes to this folder only
2. i tried to copy and move an unencrypted (normal file) file to that folder and the result is it is always encrypted.
I think it should
not be encrypted since i only encrypt the folder and not the subfolders and files. maybe im missing something. is there another way to enable or disable a folder to encrypt files?
