sendto filename length

[sttrebo]

I'm sure I'm missing something simple, but I can't seem to find an answer. I am working on a small script that is called from windows7 sendto context menu. What I want it to to is:
Select a file in explorer
right click and select sendto and send it to my ahk script. this works just fine.
in my script i have:
full_inputfile = %1%
everything works great as long as the selected file is only 8 characters long. but if the file is over 8 characters long, then the short 8dot3 is fed to my script. for example:

if i select 1234.jpg then 1234.jpg is fed to my script
if i select 1234567890.jpg then 123456~1.jpg is fed to my script

how do i fix this?

thanks

You may convert 8.3 filepath to longpath as follows:

Loop, %1%, 2
full_inputfile := A_LoopFileLongPath
MsgBox % full_inputfile
