Building fails and gives this error... Help translating?

[NIOS]

When I attempt to build my game, it fails and does not create an Exe, but takes the time to pretend it will. I have determined which scene is the culprit, but I still do not know why it crashes. There are two errors. This is the shorter one…

Error building Player: IOException: Win32 IO returned 112. Path: C:\Program Files\Unity5\Editor\Data\PlaybackEngines\WindowsStandaloneSupport\Variations\win32_nondevelopment_mono\player_win_x86.pdb" or "Temp\StagingArea\player_win_x86.pdb

I hope someone can tell me what is wrong, as I am at a standstill until I can fix it. Thank you.

PS
The longer one, if you want it…

According to MSDN, error 112 means:
ERROR_DISK_FULL
112 (0x70)
There is not enough space on the disk.
Is your disk full by any chance?
