Well, i can actually create a directory with any reserved name - you just need to know the right command. For example in a command prompt you can use the following command to bypass the check for reserved file names and folders.
C:\>mkdir \\.\C:\COM2
On the flip side of things, you can delete any folder/file with a reserved name by bypassing the check for reserved names.
C:\>rmdir \\.\C:\COM2 /S
The flag /S removes all directories and files in the specified directory - typically used when ya want to delete a whole tree.
I thought I'd explain some of the reasons behind why certain file names are invalid.
For those familiar with Unix it should be obvious, but for those not aware; to Unix a device and a file are essentially analogous, and programmatically they can be treated as such. Windows has reserved files that constitute special devices, so in effect you have a pseudoUnix architecture. CON is simply a filename for the console device; LPT1 is simply the filename for the first LPT port, COM1 for the first COM port, etc. These are files that have special treatment by the OS in that they are analogous to the devices themselves. This allows programmers to easily implement i/o routines using these devices. For example, I can do this in Windows:
CreateFile("COM1"...);
to easily read from the first COM port programmatically. I can do the same for any of the reserved files. You can also do something like this at the console:
type somefilename.txt > LPT1
To redirect the stdout to the first LPT port. Last example:
type COM1
this will cause any input from the COM1 port to be sent to the program type which will, by default, output it to the console; in other words, you can easily see the contents of the data in the buffer.
I hope this helps clear it up a bit for those interested. I can expound on anything if anyone requires it.
