Use the numerals 1 through 9 in conjunction with the asterisk (*) and the equal sign (=) to identify the part of a filename you want to keep or strip out when transferring it.
For example, if a host filename has three parts, such as Test.Text.Demo, and you want to keep just the second and third components of the file name when transferring it to your PC, you would use this condition:
*=1.*=2.*=3 (host file) --->*=2.*=3 (PC file)
which in this example would yield Text.Demo.
