Set here which folders and files should be hidden and shown.
Each entry can contain multiple patterns, separated by white spaces or commas,
each one describing a set of files or folders that should be hidden or shown.
The character 
* is a wild card representing any number of any characters,
and can be used anywhere in a pattern.
For example, the sequence 
*abc def*ghi* contains two patterns, indicating
all occurrences with either: 1) "abc" in the end; or 2) "def" in the beginning,
followed by "ghi" anywhere.
First, all occurrences indicated in 
Hide are removed. From the remaining
occurrences, only those indicated in 
Show are shown. By default, all
occurrences are shown, so an empty 
Hide means remove nothing, and
an empty 
Show means show everything.
Folders
By default 
Hide is set to 
.*, to hide all dot folders.
Files
By default 
Hide is set to 
.*, to hide all dot files.
