The temp files are used by AjaxUploader internal. Once the files are uploaded, the temp files will be removed from your server automatically.

 

>>Say the user was uploading a file called: test#abc%123.xls I want to rename the file to be test_abc_123.xls when it gets saved to the destination folder.

 

Please use the .CopyTo method and rename the uploaded files.

 

For example:   //args.CopyTo("c:\\temp\\test_abc_123.xls");

 void Uploader_FileUploaded(object sender, UploaderEventArgs args)
        {
            Uploader uploader = (Uploader)sender;
            InsertMsg("File uploaded! " + args.FileName + ", " + args.FileSize + " bytes.");
            
            //Copies the uploaded file to a new location.
            //args.CopyTo("c:\\temp\\"+args.FileName);
            //You can also open the uploaded file's data stream.
            //System.IO.Stream data = args.OpenStream();
        }
