I have 60.000 html files. I must delete first 5 lines and last 8 lines in each files and save them. I cant open them same time because of the number of the files. So I have to open, delete, save and close them one by one. My text(html) editor is a spesific program (textpad) and it supports "delete line" feature. its shortcut is ctr+E and "close file" shortcut is ctr+w. All files are in same directory and I can rename them consecutive with the other program.(so to rename with macroexpress is not important and I am not asking this). thanks for possible answers and sorry my english. best regards.
