Searching a drive for a single file there is a easy way, you can use the software "Everything" its free and is great to find files. You can run a external shell cmd from Autocad.

Everything - voidtools

es.exe dwgname.dwg -full-path-and-name >d:/acadtemp/dwglist.txt

The dwglist.txt will have all the dwg locations on all drives indexed by Everything.

You need this also Command Line Interface - voidtools

I need a pure LISP (AutoLISP) solution without VisualLisp if possible.

Check this post and solution from @doaiena

What software do you use that you need solution in vanilla autolisp. Without using vl functions solution is impossible.

What I posted is pure old lisp uses the SHELL command. You do need to download the program Everything it is well worthwhile having finds files instantly compared to explorer that works like 50% of the time.

(command "._shell" "es.exe dwgname.dwg -full-path-and-name >d:/acadtemp/dwglist.txt")

Hak_vz thanks for update had a look.

Also "How to check where is URL" and then "if there is a file with the given name on the server?" which one is it or both ?
