can you create Folder?

It is looking Funny!

So try to create these folders (or files)

CON, .CON , CON. ,COM1 ,COM2 , COM3 ,COM4 ,LPT1 ,LPT2 ,LPT3 ,PRN ,NUL ,AUX

Once Check it Out.

It is impossible.

Interesting !

You aren't allowed to create folders with names that are the same as the ones that have been used for various devices on a PC since the DOS era.

"CON" refers to "console" in DOS.
"PRN" refers to "printer,"
"LPT1," "LPT2," etc., and "COM1," "COM2," etc. refers to the communication ports.

The bug has been tried and tested in both Windows XP Home and Professional. If you try to make a folder named "CON" (case insensitive), Windows XP renames it back to what it was. So creating a new folder with the name "CON" just renames it to "New Folder".

The bug seems like a variable that got treated as a string or vice-versa. Trying to create the folder from a cmd prompt failed with an error "The directory name is invalid.".

This also works when you try to create a file called "CON", or "CON.". ".CON" shows up the way it should.

Methods To Create Above Folders:

Method 1:

STEP1: goto command prompt
STEP2: type in prompt e:\> ((mkdir \\.\e:\con))
STEP3: verify by typing ((dir \\.\e:\con))
STEP4: delete the file or folder ((rmdir \\.\e:\con))
Note::Not necessary for to go only E:,u canm create in any Drive.

(This method is bulky and confusion. So You can Use)

Method 2:

Create Folder
While name Type CON and then stroke the key ALT+0160 on numeric key pad.
(CON -> ALT+0160)
Then you can create CON folder and other described folders.

It means that when you type a folder name with simple
ALT+0160 you can create empty folder.
There is no name for a folder.
Here we are using "CON " (CON with space).
This is the tricky logic here.

Ten tips to keep your computer running smoothly:

1. Never, never, turn your computer off with the power switch until Windows has shut down.
The one exception to this rule is when your computer locks up and your hard drive is not running (hard drive light is not blinking). In this situation, you can turn the power off without harmful effects to the hard drive. As cutting the power can also result in lost data or Windows files, you should only do this when you have to.

Following this rule will prevent permanent hard drive defects caused by the hard drive heads contacting the surface of the drive disc, and it will prevent a host of Windows problems.
Whenever possible, recover from crashes by pressing the Ctrl + Alt + Delete keys at the same time. Press them again to reboot your computer.

2. I highly recommend that you purchase an UPS (uninteruptable power supply)

This will keep your computer from crashing during power outages, and will protect your computer from low and high voltage occurrences.
An UPS is far superior to a surge protector and will save your computer from almost any power type of disaster. (See #1 above for what happens when your computer crashes.)

3. Backup, backup, backup:

any data you cannot afford to lose to at least two separate physical drives. So backup data to floppies, Zip disks, CD-RWs etc.
The time to backup is when you create something you can't afford to lose. Don't wait until tomorrow.

4. Run Scandisk and Defragment at least once a month:

This will keep your hard drive healthy and prevent crashes.
Alternatively, purchase Norton Utilities and use it to keep your hard drive healthy.
Or Do like this,
right click on my computer,
click on manage,
here you can see
a tree like structured links, click on Disk defragmenter.
and click on specified drive and click on analyze and then click on disparagement.

5. As each new Windows program is installed and uninstall ed, it leaves behind parts of itself that can slow down or crash your computer:
These are mostly .dlls and other shared files.
It's also very possible when uninstalling a program that needed Windows system files can be deleted. When your computer asks if you want to uninstall shared files it's usually safest to say no -- even if your uninstall program claims the files are not being used.
Old Windows drivers can be found by booting into Safe Mode, then opening Control Panel/System/Devices and ridding your system of old drivers.

Or Your registry hierarchy gets unknown application values. This cause system registry may breaks down.

6. Do keep at least 100 MBs of your C:

If you use Windows Me or Windows XP then you should have 200 MBs of free space on your C: drive.
If you do not have enough free space you will choke Windows and it will start dumping data to your hard drive, or it will just get really, really, slow.
Use the ADD/Delete tool in the Windows Control Panel to delete unneeded programs from your drive.
You can also use Cleansweep included in Norton Utilities to clean up your drive. If you do use Cleansweep or another hard drive cleaner, do not delete shared files unless you back them up.

Use Ccleaner software for deleting temporary files.

7. Do not let a lot of programs load up when you start your computer.

They use valuable memory and Windows Resources (Windows internal workspace).
All programs in your Windows System Tray (in the lower left of your screen) are running on your computer. Close them if you don't need them or run them and configure them not to load when you boot up.
Other programs running in the background can be found by pressing Ctrl + Alt + Delete at the same time.
or Do like this
go to start menu,
click on Run,
type the command "msconfig"(without qoute)
click on "startup" menu
and now you can enable or disable required programs at srart up.

8. Do use a virus checker regularly.

Everyone should use a virus checker.
The best type of protection is continuous monitoring from a dedicated anti-virus program like Norton Antivirus.
The second best thing is to use is the free online virus checker Housecall provided by Trend Micro.
Some of anti virus softwares are:
AVG,Avast,Norton,Trend Micro Internet Security,Clam Win,McAfee,Spyware Doctor with antivirus,Kaspersky,pondo

9. If you have a high speed Internet connection you need a firewall program.

A firewall program keeps those who want to hijack your computer from gaining access to your system. You really do not want someone else running your computer.

You can use Zone alarm or Comodo (Open source) firewall third party softwares.

10. Keep track of the software disks you receive
Keep track of the software disks you receive with your computer and new peripherals. These disks contain valuable software drivers and programs for Windows and are needed when Windows must be reloaded. Keep these disks and your Windows software disks in a safe, dry, place -- you never know when you will need them.

Difference Between Hybernate and Standby

Standby:

Your machine recovers quickly as your data is stored in RAM. The slower part is waking up the peripherals. Although your machine is in "standby" the power has been cut to items such as your hard drive and monitor. You're running your machine in a very low power mode, but it is still on. This mode can be useful if you're on a notebook and need to conserve your battery while you step away.

Hibernate:

The big difference is that your PC has shut down and is not pulling power. Another difference is that your data is saved to your hard disk and not RAM. This makes it a safer, but slower option for shut down and resume.

Note:
Not all PCs have the capability and are configured to Hibernate. If yours is, to see the Hibernate option on your XP shutdown screen, hold down the Shift key when you shut down.

Some comments up on hibernate and standby:

comment 1:

I've always loved hibernate. It's great for when you are running out of power and don't want to lose what you're working on.

Still, I used hibernate for a while on my home machine, but my wife hated it because it took to long so I switched it to standby. It's much faster, but I constantly get these annoying errors about data lost on $DMFT or something like that.

comment 2:

I prefer Hibernate for my desktop, as it allows me to pick up right from where I left off. Slow as a it may be, it is not nearly as slow as a clean boot.

comment 3:

It uses about as much hard disk space as you have RAM. Thus, if you have 1 GB of RAM, you can expect hibernating to take about 1 GB of hard disk space. This will be cleared up when you bring the system back up. Whether this is an "enormous chunk of your hard drive" depends on your particular system and your definition of "enormous".

My choice is depending up on your hardware configuration and your flexibility you use hibernate or standby

Clean your computer regularly and give more life

I have a dirty secret. I've never cleaned my computer. Sure, I've dusted my monitor, but I haven't taken off the cover or tried to reach the crumbs lurking inside my keyboard.

"Your computer could fry if you don't keep it clean," says Jonathon Millman, chief technology officer for Hooplah Interactive.Dust clogs the vents behind your computer, which causes your CPU to heat up—and heat is the biggest cause of component failure in computers. Regular cleaning could save you costly maintenance fees down the road.
Keep your computer in tip-top shape by following Millman's guide to a spotless computer system.

Preparation:

• screwdriver
• can of compressed air (available from computer dealers or office-supply stores)
• cotton swabs (do not use a cotton ball)
• rubbing alcohol
• paper towels or anti-static cloths
• water

Note: Always turn your computer off before you begin and unplug all the cords.

STEP 1: Inside the case:

Using a screwdriver, remove the side of the case that's opposite your motherboard. Touch as little as possible inside the computer, keeping fingers away from cards and cords.

Blow air around all of the components and along the bottom of the case, keeping the nozzle four inches away from the machine. Blow air into the power supply box and into the fan (from the back of the case). Lastly, blow air into the floppy disk and CD drives. Wipe the inside of the cover with a lightly moistened cloth before replacing it.

Millman recommends doing this every three months if your case sits on the floor, if you have pets that shed, or if you smoke. Otherwise, every six to eight months is fine.

STEP 2: Outside the Case:

Run a cotton swab dipped in rubbing alcohol around all of the openings on the back of your case. Give them one swipe with the damp end of the swab and one swipe with the dry end. Do this as often as you clean the inside of your computer.

STEP 3: Keyboard

Turn the keyboard upside down and gently shake it. Most of the crumbs and dust will fall out. Take a can of compressed air and blow into and around the keys. Next, take a cotton swab and dip it in rubbing alcohol. It should be damp, but not wet. Run the cotton swab around the outside of the keys. Rub the tops of the keys. If you have a laptop, follow the same procedure but take extra care with your machine. Do this monthly.

STEP 4: Mouse

Rub the top and bottom of your mouse with a paper towel dipped in rubbing alcohol. Open the back and remove the ball. Wash the ball with water and let it air dry. To clean inside the mouse, dip a cotton swab in rubbing alcohol and rub all of the components. Scrape hard-to-remove grime with your fingernail. Finally, blow air into the opening. Replace the ball and the cover. Do this monthly.

STEP 5: Monitor

Moisten a paper towel or a soft, lint-free cloth with water. (You can also buy monitor cleaning products at computer-supply stores.) Don't spray liquid directly onto the screen—spray the cloth instead. Wipe the screen gently to remove dust and fingerprints. Never touch the back of the monitor.

I don't know some file formats

You know a software is the collection of different types of files.

One day when I was looking deep into a software I saw a file with the extentions XXX.nb.
It is a unknown file format for windows.
How to open?

Just I searched the web and I got a great website dedicated for only file extensions.

It improves your knowledge about different file formats in windows.

How to Start Multiple Applications via Start Menu

Whenever we start a program via the start menu, the start menu will automatically disappear after we've clicked on one of the program shortcut. So when you need to launch another program, you need to open again the start menu. Meaning, the start menu can only open one program one at a time (by default).


Luckily, there is a way to prevent start menu from closing every time you open a program shortcut by holding down the SHIFT key while clicking on the shortcut. This can help you save time if ever you need to open different program, by holding the SHIFT key the start menu will not disappear after you open one program.

This also works when you want to delete different program shortcuts in the start menu.
