Exclude files		In this field, type the masks that define the names of files and folders to be excluded, for example, *.min.js. Use semicolons as separators. If the name of a file matches any of these patterns, the file is treated as excluded. If the name of a folder matches a pattern, all the files in this folder and in its subfolders are marked as excluded.
