How to retrieve a deleted program file from the lego NXT I have been programming a complex file for my Lego Mindstorms NXT. I accidentally deleted my file from the PC, but it is still available on my NXT brick. Is there any way that I can retrieve the file from my NXT and continue programming it? The file is complex, and it will be difficult for me to recreate it. Also, if this helps (or places restrictions), I made the program with the EV3 software (as is backward compatible - and I do have the NXT software also). I haven't tried any methods (I don't know any to try) so I can't tell you what doesn't already work for me.

Also, the PC I used is not mine, so I do not have a way to recover the file from that PC. If I could recover it from my NXT I can get the program on my personal computer.
Thanks!
NXT programs are compiled into a program the brick can run. It might be possible to pull the compiled code off the brick, but I'm not aware of any disassemblers or decompilers for the compiled programs.

I think your best chance at recovering the program would be to try to recover the deleted file on your PC with a deleted file recovery program.
