In order to scan files with Lansweeper, you need to define the exact path and file name under
Configuration\Custom Scanning, section
File Scanning. Searching for files on your computers isn't possible with Lansweeper as this would dramatically increase the load on your client computers and your network.
You might be able to create a script which will be deployed to your computers, locally searches for PST files and writes a result into some txt file on your network.
