I am having a problem with Mastercam temp files. I have a dual xeon 3.6 with a Solid State drive on which mastercam is installed. I have another IDE drive that holds all my .mc9 files. I have made adjustments to Mastercam so that all the temp files are written to the Solid State drive (this was to speed up the performance). I all of the sudden show a .tmp file that is being written to the C:Documents and SettingsUser AccountLocal SettingsTemp directory. This file is called DC40.tmp I have other computers that are setup the exact same way (hardware and software are identical to the "T"). They show the same problem as well only the name is slightly different (Ex. DC27.tmp) This file is anyware between 1.4GB and 60MB. My question is how do I move this file or keep mastercam from writting it? Were is this file coming from or what is it used for. I need to have someany light shead on this. I have 16 MILL3 users that need this attended to immediatly! Any advice would help. Thanks
