I'm wondering how many users of Intralink and other PTC data management products use it for storing files other than Pro/E files, specifically AutoCAD. We use Intralink 3.4 and store some AutoCAD, Word, and Excel files in it. Occasionally an AutoCAD file is imported which will not open. I know it's not a configuration issue because most files open correctly, and the filenames look legitimate (no spaces). Is this a common issue and is there a solution?
