I have a file I created and edited with textedit. I saved the file many many times. Textedit crashed and I rebooted and the file it entirely gone.
What happened? Is there a way to recover it?
A bit more background on the problem and my machine: I have a macbook air; it's 2.5 years old and has OSX 10.9.5. It has recently had another issue which I haven't been able to diagnose: The hard drive is frequently filling up after a few hours or days without a reboot, and no new downloads of more than a few MBs. After I reboot, some, but not all, of the space is recovered. Since I began having that issue, I've deleted 10+ GB of data over the course of a few weeks, and yet my hard-drive has less space available than it used to.
The crash happened when I had recently received a warning about my start-up disk being full and had only ~200MB remaining available space, according to Finder.
