I will use this feature in an App's "Start In" parameter.
I want to use
CUR_LOC but if it's not found then I want to use another/default location.
Something like this:
{CUR_LOC|C:\another\location\}
If I run a command, it will first check
CUR_LOC, if it's found, it will use
CUR_LOC,
If
CUR_LOC is not found, then it will use
C:\another\location\ for "start in" location.
Example, I use WGET (downloader):
If I give URL and I'm in a folder, then it will download in CUR_LOC, otherwise it will download in the other provided location.
