Arduino IDE deleting project when disk is full.

I was getting a compile error, so I relaunched and the code is gone. Like nothing at all, not even the default classes. I assume it tried to save when I closed the IDE (despite there not being any dialog boxes) and corrupted the file :/ the ino file still exists, but it is now empty (0 bytes). I also tried looking at the compiling folder in %appdata%/local/temp, but it was empty. I have very little space on my C drive, so that may be why, but I am extremely frustrated after losing my school project.

Start by reproducing the reported failure with very little space on the C drive, using the affected .ino file and checking %appdata%/local/temp as described. Trace what happens when the IDE closes or saves after a compile error. Done means a disk-full condition no longer leaves the project’s .ino file empty or loses its contents.
