Why folders with the name CON can’t be created in Windows???

In this post i'm going to tell you some interesting facts of windows. As we  making a folder with the name con can not be possible in windows. Some people don’t know why they can’t create it? Very few know that they can still create it someway. But don’t know why are they supposed to do exactly like that.

Now, After reading this ,you will become one of the rest.

Not only CON, we cannot create any of these

CON, PRN, AUX, NUL, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, LPT9 and more

The reason is that con, prn, lpt1..lpt9, etc are underlying devices from the time dos was written. so if u r allowed to create such folders, there will be an ambiguity in where to write data when the data is supposed to go to the specified devices. In other words, if i want to print something, internally what windows does is — it will write the data to the folder prn (virtually u can call it a folder, i mean prn, con, etc are virtual folders in device level). So if we are able to create con folder, windows will get confused where to write the data, to virtual con folder or real one.

So Now, Try this…
Open the Command prompt by Start -> Run and type cmd

Code:
C:\> md \\.\c:\con

Now, Open My Computer and browse through the path where you created CON folder… Surprising?? Yeah, you have created it successfully
Now, try to delete the folder from My computer
OOPS!!! You can’t delete it…

Now, try this in command prompt console

Code:
C:\> rd \\.\c:\con

Yeah!! You did it…

TECHITWEETS::

1.Instead of closing the whole window this will close internal windows within the current program. For example if you have multiple windows open in one instance of Microsoft Word this will close them one at a time. The best part is this works for the tab browsing that has come in to play in recent browsers. The key press closes the active tab you are viewing!

2.Custom Shortcut Keys!
To setup a shortcut key to your favorite program first you need to right click on the shortcut icon you commonly use and then press on properties. Click on the Shortcut' tab and there will be a text field called 'Shortcut key'. Simply click in that and enter the key press you wish to use. Press OK and that key press is permanently associated with that program. This is very handy for many things such as opening word or opening your favorite game!

Set a new Windows Explorer launch folder

When you run Windows Explorer, it always opens to the Libraries folder. That's fine if you use Microsoft's default file organization, which designates Libraries as the overall container for your folders.( the below shown folder comes in your task bar which by default when you clicks opens to library)

Changing the default Explorer location.

But what if you don't? You might prefer to have Windows Explorer open to Computer or any other folder you choose. Here's how to do it:

1. Right-click the Windows Explorer icon on the taskbar (it's the one that looks like a folder), and then right-click the Windows Explorer icon from the context menu that appears and select Properties. The Windows Explorer Properties dialog box appears.

2. You'll have to edit the Target field on the Shortcut tab of this dialog box in order to change the default location at which Explorer opens.

If you want Explorer to open to a specific folder, simply enter the name of the folder, substituting your folder name for Folder, below, like this:

%windir%\explorer.exe c:\Folder

So to open Explorer to the folder named users(i am taking an example you can choose any other folder of c drive), you would type this in the Target field:

%windir%\explorer.exe c:\users

here are some other locations that you can choose your windows explorer folder to open by default whenever you click on to it.

• Computer: %windir%\explorer.exe ::{20D04FE0-3AEA-1069-A2D8-08002B30309D}
• My Documents:%windir%\explorer.exe ::{450D8FBA-AD25-11D0-98A8-0800361B1103}
• Network: %windir%\explorer.exe ::{208D2C60-3AEA-1069-A2D7-08002B30309D}
• Libraries: %SystemRoot%\explorer.exe

3. After you've changed the Target field, click OK. Next time you launch Windows Explorer, it will open to the new location you've designated
