I am rethinking what I am trying to achieve. The purpose of this exercise is to
update file paths stored in 4D for thousands of architectural drawings when the
folder containing all these nested drawings is moved to a different location
locally or to a different machine.
Ultimately the paths stored in 4D are sent to a web site for display in an end
user’s browser.
So currently the paths only need to be updated in 4D when the drawings folder
is moved or reorganized.
I am now thinking that maybe I should use LEP to get the current path when 4D
gets the http request for the file, rather than relying on the path stored in
4D. A single call to LEP is almost instantaneous so this should work fine. This
way I would not have to worry about where the end user puts or organizes the
drawings as long as they are located on a drive that 4D can see.
Ok, say I go this route, it should work great on the Mac, but what about
windows. Is there a command similar to mdfind in the windows environment?
