I have a rather large assembly in a mold design. This moldwas designed using SW 2007 then it got brought over to 2008. I amnow making some changes, ever so often I get the Unexpected FileFormat error. the window that pops up says ok, well once it doesit, this window pops up everytime it opens a file, there areseveral files. I reboot the computer and it will read in the files.

Does anybody know a work around on this? Thanks for yourinput.SolidworksGeneral
