discoverd the 3rd way - 1. In qdl window add a downlod link for the same file and pause the download. 2.go to /MyDocs/QDL/incomplete/ there are 2 files. 3.copy the current file name in clipbord and rename it with any name 4.rename old file with copied name in clipbord(current file name). 5.go to QDL window and resume the download (can use the way 1st or 2nd mentioned by marxian) its working for me. wht u say
