Anyone Using HTML5 Remote App with File Up/Download and EXCEL files? When Excel saves a file the default behavior is: 1. Save a file as .tmp 2. Rename the .tmp to .xlsx This is default and imho cannot be changed. When a user saves a file out of excel directly to html5-Download folder, html5 clients cuts it and forwards it to the users browser. In this case it cuts the .tmp file. Excel shows an error, when doing #2 and wants to rename .tmp to .xlsx as the file is missing. The result is an error in excel and a user that gets a browser file download for XYZ.tmp Any idea? ^^
