The 'Toolbox' Icon that can be found on Orbitron's "Main" tab, leads to a further set of tabs. One of them is called "Miscellaneous".

The bottom right hand panel of the Miscellaneous tab allows you to set the directory that will be used for element sets. If you also tick the box marked "Personal TLE directory", it will automatically store Spacetrack, Celestrak, element sets there too rather than under the Orbitron directory in Windows/Program Files.

The directory you choose can be anywhere you choose such as under "My Documents" or the equivalent in later Windows versions.
