Remove illegal characters from a file name but leave spaces

November 30, 2023 by Tarik

Illegal characters are listed here. To replace them use this regex /[/\\?%*:|"<>]/g like this:

var filename = "f?:i/le>  n%a|m\\e.ext";

filename = filename.replace(/[/\\?%*:|"<>]/g, '-');

console.log(filename);
