EfsInfo Syntax

efsinfo [/u] [/r] [/c] [/i] [/y] [/s:Dir] [Pathname [...]] [/?]

Where:

/u: displays encryption information about the files and folders in the current folder. This is the default option: running efsinfo without switches produces the same output.
/r: displays recovery agent information.
/c: displays certificate thumbnail information.
/i: continues performing the specified operation even after errors have occurred. By default, EfsInfo stops when an error is encountered.
/y: displays the current Encrypting File System (EFS) certificate thumbnail on the local computer. The files specified might not be on this computer. If no items are returned, there are no encrypted files on the system.
/s:Dir: performs the specified operation on directories in the given directory and all subdirectories.
Pathname [...]: specifies the path of one or more files or directories for which to display encryption information.
/?: displays command-line help
