I edited a excel spreadsheet which came as an attachment to my email - without first saving it to a local directory in my PC. Now I don't seem to find the edited file When I open the attachment now, I see the original un-edited file. I searched the temp directory which stores the attached files - C:\Documents and Settings\username\Local Settings\Temporary Internet Files. The edited file is not in there. Also the attachment files temporarily stored in this directory do not show up in the list shown when I do a search for files (Search - including Hidden files). Help !!! Any other directories that the file may get stored after editing it ?
