If these don't help, you can always open the general field with <Ctrl><Home>, copy it to the clipboard using Edit->Copy or <Ctrl><C>, and paste each one to an image editor, or Word, or anything that can show bitmaps, then save it to a file from there.
Sir, Thanks for your reply . Ihave tried the procedure but was unable to make bmp file as the File format of the FTP File is not the same. AS per the article it is assumed 599 bytes are fixed for header, but in my FPT File its unable to find the header size. kindly suggest me what to do.
