Plesk file manager error

ERROR

File manager error - permission denied Does anyone know the user account that plesk is using for file manager? I'm getting the error below for any domains in my server:

FileList::init() failed: ls_dir_wrapper() failed: Unable to get file (C:\inetpub\vhosts\******) attributes: (5) Access is denied.
---------------------- Debug Info -------------------------------
0: C:\Program Files\SWsoft\Plesk\admin\htdocs\filemanager\filema nager.php:677
require()
1: C:\Program Files\SWsoft\Plesk\admin\htdocs\plesk.php:17

SOLUTION

Make sure that psaadm has read, read and execute and list folder content permissions for %plesk_vhosts% folder

Try to perform "check permissions" for domain from Plesk -> domains page
