Be sure to test for the OS before attempting this. Never say your code
will never be used on Linux/Mac/... and spawns like this will cause
trouble later on. Use !version.os_family or !version.os to select the
correct OS you will use this on. In your case you may want to provide
this functionalty only on Windows (at least I think that that is the
correct identifier, check for yourself):
if !version.os_family eq 'windows' then begin
spawn, notepad.exe c:\myFolder\myFile.txt', /noshell, /nowait
endif else begin
print, 'functionality not supported'
endelse
By the way, on the mac the command would be:
spawn, "open '" + filepath +"'"

Yes, you can easily do that. Try:
SPAWN, 'notepad.exe c:\myFolder\myFile.txt', /noshell, /nowait
