Continue with invalid file extensions

If the WinZip file contains many files with extensions that are invalid or too long, WinZip will display an error message and give you the option to skip the file. Unfortunately, if there are many such files, WinZip does not provide the option to skip all future files with invalid extensions. To unzip the remaining files, you must alternate between clicking two buttons for each bad file. For a zip file with many such invalid filenames, this generally means you cannot unzip the directory that WinZip created in the first place.
