* It is very important to keep '\\' out of the folder path, because it allows
|
|
* for all sorts of behavior (like "..\foo" or "D:\ack") that the caller
|
|
* might not be expecting. For example, if it's displaying a tree, it
|
|
* might assume that the folder goes under the currently selected node.
|
|
*
|
|
* Under WinNT, '/' is regarded as equivalent to '\', so we have to block
|
|
* that as well.
|
|
*
|
|
* Other characters (':') are also dangerous, but so long as we start with
|
|
* a valid path, Windows will prevent them from being used where they are
|
|
* inappropriate.
