why my disk space fill up



I run LiveCycle ES workbench a couple of times and couldn't let it start. It stops at retrieve server configuration. And my C drive originally has 10G free space, but finally 0 free space, could you tell me any files write to my disk? Can I delete them? I have no more disk space and couldn't run the program, even restart computer. There's 1G files generated in C:\Document and Settings\bwang\LocalSetting\Temp, can i delete all the files there. Got to be somewhere else have temp files, otherwise my 10G free space won't gone.
