Create File and Folder with Name "CON" in Windows
Most of people wondering, when hear that we cannot create a folder with the name CON.
Simple ppl dont know why they cant create File named with "CON"?
Very few know that they can still create it someway. why are they supposed to do exactly like that..
Now, After reading this tutorial, you will become one of the rest.
Not only CON, we cannot create any of these:
CON, PRN, AUX, CLOCK$, 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...
C:\> md \\.\x:\con
Note: x: represent the Drive letter where want to create. (it may be C:, D: and So on)
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 cant delete it...
Now, try this in command prompt console

Laptop Touch Pad Click option doesn't woked
Last day when I am working on my QT (Its name of my laptop).
A problem is occurred, that is after restarting windows touch pad of laptop
doesn’t work perfectly. There was some error, It works well for moving the
mouse pointer. But click and double click operation cannot performed by touch
pad, even left and right click button works fine. I was shocked. I was trying
to sort out the problem by control panel, there was nothing to do. Finally I restored
the computer at previous time. It still not worked. At last I googled the
problem. I searched a lots of solution but that was not worked. Suddenly, I
think why not download the touch pad drivers. In some solution I found that if
device setting tab available in mouse property then our problem could be solve.
That very option didn’t appear in my mouse property. So, I am tensed. After
then I downloaded the driver called
Synaptics
Pointing Device Driver
Any one can download it from there Laptop manufacturer website or
anywhere. Here is the link that can be also work for most of laptop (HP, Acer,
Lenovo, Sony, Toshiba and more)
After installation of software restart you PC and open the mouse device setting by
Start | Cotrol Panel | Hardware and Sound category | click on "mouse"
OR
Start | Type “main.cpl”
In both case a dialog box will appear like
Now click on Device Setting tab. Then following dialog box will appear that is use to enable and disable the pointing devices. We can also hide / show driver icon from system tray using following box.
For my problem
I used the settings.. button then another window will open
Here taping option provide a lots of facility from where, I just select enable tapping option and my problem had been solved.

Note: Snaptics driver can not only used for touch pad of
laptop but also used for other pointing devices.
From this setting we can control the speed scroll, gestures
and many more setting easily that increase the value of touch pad. Some video
tutorial also included that can help in understanding the touch pad technique.
