Hope it helps and please share if you have a better solution. xc - exclude changed filesįor example, to copy all files from folder A to folder B excluding all files that have the newer timestamp. You can use the following switches to skip certain files. Or, use a much powerful copy command line alternative instead, i.e. The %~nx in the command is to strip off the folder info from the variable %f so you only get the filename as the result. C:\Program Files\WinZip\wzunzip docs.zip E:\Documents. Example: We can unzip the file docs.zip to the directory E:\Documents as follows. destinationfolder is the directory where you want to keep the unzipped files. FOR %f in ("frompath\file\*.*) DO IF NOT EXIST "topath\%~nxf" COPY "frompath\file" "topath\file" The command for unzipping files is: C:\Program Files\WinZip\wzunzip zipfilename destinationfolder. If you need to copy a folder to another location but do not overwrite the files already existed in the new location, here is what you can do. echo n | copy /-y "frompath\file" "topath\file" Switch options can be combined to save command line length. Wildcards or filenames with spaces must be quoted: 'DirProgram files' Dir'Program files'. The switches and other filenames can be in any order. The 'basearchivename' must be the first filename on the command line after the command. IF NOT EXIST "topath\filename" COPY "frompath\file" "topath\file"Ī friend of NoW, Glenn Reimche, shared a much better way using copy command line without the IF statement. Command is the first non-switch argument. You can either use the IF statement to copy the file only when the file does not exist in the destination. Or, if you are using command line copy, you can answer N to bypass these files that are already existed.īut how can I do the same through a batch file using any copy command line? If you are copying files using drag-drop or copy/paste, you may simply choose “Skip this file” or “Skip these files” option to not overwrite the files that are already existed at the destination folder.
