I have a client who had a problem with this on Windows 98 with NAV corp 7.6. It has been a while since this happened so my memory is not real clear but it had something to do with the log files that NAV created. Check your NAV directory for log files and you should find the culprit. -----Original Message----- From: Christine Easton [mailto:christine.easton@xxxxxxxxx] Sent: Friday, September 19, 2003 10:57 AM To: thin@xxxxxxxxxxxxx; Windows2000@xxxxxxxxxxxxx Subject: [THIN] OFF-Topic I have a windows 2000 box with exchange 5.5, Nav corp 7.6. My c:\ keeps filling up and I have no idea where the space is going. My exchange files are on the d:\. There is nothing in the Norton quarantine. Does anyone have any ideas?
