You can only encrypt files and folders on NTFS file system volumes.

Files or folders that are compressed cannot also be encrypted. If you encrypt a compressed file or folder, that file or folder will be uncompressed.

Files marked with the System attribute cannot be encrypted, nor can files in the systemroot directory structure.

When you encrypt a single file, you are asked if you want to encrypt the folder that contains it as well. If you choose to do so, all files and subfolders that are added to the folder in the future will be encrypted when they are added.

When you encrypt a folder, you are asked if you want all files and subfolders within the folder to be encrypted as well. If you choose to do so, all files and subfolders currently in the folder are encrypted, as well as any files and subfolders that are added to the folder in the future. If you choose to encrypt the folder only, all files and subfolders currently in the folder are not encrypted. However, any files and subfolders that are added to the folder in the future are encrypted when they are added.
