why we can not create a folder named "con" in windows?

I tried to create a folder named con in windows 7 and I wasn't able to do that it says "specified device name is invalid" what is the secret of this problem?

See the MSDN naming of files, paths, and namespaces:

Do not use the following device names reserved for the name of a file:

CON, PRN, to THE, NUL, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, and LPT9. Also avoid these names immediately followed by an extension; for example, NUL.txt is not recommended.

This applies to files, too.

  • Why I can not create a new folder in Windows Contacts and rename it?

    I keep my contacts in Windows Contacts, divided into folders named category.  In the past, I was able to press the button "New folder" to create a new folder, and then rename the folder.  Now, I can create a new folder, but Windows doesn't allow me the no - name.  As soon as I type the name of the new folder and press ENTER, it goes back on behalf of the "new folder". Can someone explain what happened?

    If possible, although I honestly don't see how the shortcut should influence.  Try this, just delete your shortcut, then take the icon on the left side of the address bar of the 'work' contacts folder and drag your desktop and drop it.  This example is part of a control panel, but it works the same:

    I'm not sure that looking to the right registry key, but I certainly don't want to bother you here if you don't know what you're doing. A mistake in the registry can make your computer unbootable. The problem is that what you are trying to download is trying to download an apparently non-existent folder. I think it would be best if you have someone qualified to look at the machine. This could be a very knowledgeable friend or computer technology (as long as the friend is really competent and not just say it is). Without being able to see your computer and get the answers to my questions, I can't really help.

    What has changed between the time where things worked and the time, they did not? If things worked just a few days ago, you might want to try a system restore to that date. It is perhaps easier for you. MS - MVP - Elephant Boy computers - don't panic!

  • Why Vista WMP can't play .asf files and why MS has not created a fix for this?

    Why Vista WMP can't play .asf files and why MS has not created a fix for this?

    Hi pdaamckechnie,

    The ASF Format (Advanced Systems) is the preferred Windows Media file format. With Windows Media Player, if the appropriate codecs are installed on your computer, you can play audio content, video content, or both, that is compressed with a wide variety of codecs and that is stored in an .asf file.

    You can check the link below for more information on the types of media files that supports Windows Media Player

  • Why you can not run portable applications on RT?

    Why you can not run portable applications on RT?

    Nothing is installed on the system. That's all, flash USB, a folder or drive.
    You don't have to install anything. So why can not run portable applications on RT?

    I know exactly what is a portable application. It requires no additional drivers installed or libraries to run on a system, if one is required that they are either built into the executable and extracted the runtime or are included in the same location as the executable and are referenced from this location.

    No portable application is not somehow the operating system to display the current status, error messages or generate logs for its operation. If it cannot accept input during its operation or generate a form of output it has no function. This is the basic description of a program to have one or the other or both.

    When you double-click an executable file is Windows (if it's the operating system) giving you the ability to open its location, see the executable file in order to select and issue the command to run. It's Windows that then loads this program in memory to run. If necessary, Windows that displays the dialog box to provide any input and display results or error messages generated by the program. If the result is a log file that it is Windows that allows access to the drive to create the file and the result is an error state in Windows that stores the status of the error, then it can be interpreted by another program. If the output is to change the status of the computer in a way, it's Windows that gives access to this device or component. The Hardware Abstraction Layer allows access to the hardware itself if necessary by a program and even that is a part of Windows.

    So I know what a laptop program is, more important still, I also know what is Windows.

  • can not find the folder under brushes in the finder

    Hi everyone im trying to clean my presets in Photoshop CS5, I recently saved the brushes that I created in photoshop and I clicked on the new folder button at the bottom to create a new folder named "My brushes" and I saved the brushes, which was ideal because he has created a line of separation between my brushes and photoshops built in brushes to keep things neat and make searching for my brushes less complicated, because before he confused them in alphabetical order with the brushes included in the drop down menu in the control panel shapes.

    But now, I can not find this folder "My brushes" or its contents any where except in photoshop, so I can't rename the folder, delete it or backup my brushes someone know where photoshop is hiding? any help greatly appreciated

    If the library folder in your user name (the' home ', no library folder on the top level of your system disk) contains any Application Support/Adobe/Adobe Photoshop CS5/Presets/brushes?

  • Why I can not contact you with FEEDBACK REAL

    Why I can not contact you with FEEDBACK REAL? Why Firefox to 28 allows me to download files from Web page complete, but worms 30 does not work? Plugins, Addons, Internet Security are the same on both systems. I can download the files in IE but not Firefox. What gives? I use NoScript, Better Privacy, Ghostery, and Kaspersky Internet Security configured the same on both systems. The only reason I checked is because on some sites, I can't download files and point of view completely. 30 to Firefox will download but not to create a complete directory html link so that I can open and view the file.
