How do you create a hidden folder?

There are two ways:

The first way - just name the folder dot-something ex ".folder" or ".hidden". The system may not let you do this, so just go into Terminal and type:

"mv /path/to/folder /path/to/.folder".

Note: If you have a space, use a \, like this:

"mv /path\ with\ a\ space/to/folder /path\ with\ a\ space/to/.folder"

The second way is to just flag the folder as hidden, as shown:

Into a terminal, type

"chflags hidden /path/to/folder"

Use "chflags nohidden /path/to/folder" to show again.

To show hidden files/folders in the open/save sheet, press Command-Shift-.

To show hidden files/folders in Finder, go into a terminal and type:

"defaults write com.Apple.finder AppleShowAllFiles YES"

To hide, of course, type:

"defaults write ... AppleShowAllFiles NO"
