The script function GET_FILESYSTEM in combination with the File System Value 'PATH_FILE_COUNT' 
returns '1' instead of the previous and documented value of '0', when the folder defined does not exist. 
With Windows Agent version 12.2.0, it worked correctly - returned '0', 
with Windows Agent version 12.2.1, it returns the value '1'.

Example: 

:SET &TAR = GET_FILESYSTEM(WIN_AGE,'C:\Test1\*',PATH_FILE_COUNT,"STD_WINDOWS")
