You Cannot Create a Folder Named CON !!!

You Cannot Create a Folder Named CON !!!


It is fact that you cannot create a folder named "CON", nor can you rename an existing folder to "CON". "CON" and a number of other character strings are in fact reserved names that go back to the days of DOS and cannot be used to name folders or files.

Other
reserved names are:

* PRN

* AUX

* NUL

* LPT1

* COM1

* Potential drive letter - A: to Z:

* A number of others


If you try to name a folder using one of these reserved names, the name will automatically revert to the default, generally "New Folder". Moreover, if you try to use a reserved name to name a file such as a Notepad or Microsoft Word document you will generally receive an error message similar to the following:



Depending on exactly how you save the file, you may instead receive a warning message advising that a file with that name already exists. However, even if you choose "Yes" to overwrite the existing file, you will still not be allowed to save the file.
