Not sure if this might help but someone once showed me this method which checks if the file can be opened for access:-

repeat 20 times
try
open for access file x -- if this succeeds, the file is not busy.
close access result
exit repeat
on error -- file is busy
delay 3 -- times it out in 1 minute
end try
end repeat

Known issue. You have to loop-check the file sizes and compare.

I have a bit of canned code I use on a 3-second delay:

on adding folder items to theFolder after receiving theAddedItems
   tell application "Finder" to set theFolderName to name of theFolder
   repeat with x in theAddedItems
       set theFileInfo to info for x --get info for the downloading file(s)
       set theBaseSize to size of theFileInfo --get initial size
       delay 3 --wait 3 seconds
       set theFileInfo to info for x --get info again
       set theCompareSize to size of theFileInfo --get a newer size
       repeat while theCompareSize ≠ theBaseSize --if they don't equal, loop until they do
           set theBaseSize to theCompareSize --new base size
           delay 3 --wait three seconds
           set theFileInfo to info for x --get info
           set theCompareSize to size of theFileInfo --get a newer size
       end repeat --once the sizes match, the download is done
   end repeat

      --do other stuff here

end adding folder items to

Is it not faster to check for the file extension?

That only works if you only ever use Safari to download. Other applications/methods don’t use that convention. This doesn’t really delay things more than a few seconds, and unless you’re staring at the screen, you’re not really going to notice it.
