Change & Delete Windows Drive Letters with DriveLetterView


assigned drive letters 
In Windows operating systems, hard drive partitions and external drives, such as optical drives and USB flash drives, are identified by drive letters from A to Z. Some of the letters are reserved, for example A and B for floppy drives or C for the active primary partition, which typically contains the operating systems. Any other partitions or optical drives are assigned subsequent letters.
Removable drives receive drive letters based on availability. For example your USB flash drive could receive the drive letter G when it is plugged in alone, but it might receive the drive letter H, when your external hard drive was plugged in and grabbed the G first. As this demonstrates, drive letter assignments for removable drives are not permanent.
In some cases, however, a permanent drive letter assignment is desirable. Let’s say you have set up a backup routine. Your storage location is an external hard drive. You specified the path to this hard drive, assuming it would always be assigned the same drive letter. If however, another device is connected and occupies the respective drive letter, the backup may fail. To avoid this scenario, you can permanently assign drive letters to selected devices.

DriveLetterView

DriveLetterView is a freeware utility for Windows, which provides a list of currently and previously connected devices and their respective drive letters. Moreover, you can use this tool to remove devices or change their drive letter assignment. If desired, a list of all drive letters with assigned drives and other properties can be exported to a simple text file or saved in CSV, XML, or HTML format.
DriveLetterView comes in a ZIP archive and being a portable tool it doesn’t require an installation. Simply extract the files, run the EXE file as Administrator, and you will see a list of your drives, similar to the one shown in the screenshot below. Note that if your anti-virus software reports DriveLetterView as malware, it’s a false positive!

Using the red X in the top left you can delete drive letters of devices that are not currently plugged in. This way you can make drive letters available and subsequently assign them to other devices from the list.

Note that DriveLetterView cannot be used to change the drive letter of a local hard drive!

Windows Computer Management

In case you are wondering whether assigning drive letters can be done in Windows without the help of third party software, the answer is yes, this is possible. It does however require that the respective device is connected.
In Windows 7, click the > [WINDOWS] + [R] key combination and run > compmgmt.msc. Within the > Computer Management window switch to > Storage > Disk Management.

You can now right-click on any of the devices listed on the left and select > Change Drive Letter and Paths In the window that opens, click the > Change button. In the next window, select the desired drive letter and > OK your changes.

The change is instant. The next time you connect that device to your computer, it will again be assigned the drive letter you selected. Moreover, the Windows solution also allows you to change drive letters of local hard drives. Be careful though as these changes can render software unusable.

Summary

Using DriveLetterView instead of the native Windows Computer Management tool not only has the advantage that it requires less mouse clicks. In contrast to the default Windows solution, you can easily manage drives that are not currently connected, but were previously connected to your computer. DriveLetterView thus is a handy tool for those of you who frequently switch around external drives and wish to permanently assign drive letters to specific devices.

    How to use Bluetooth technology to connect laptop and cell phone?



    We can use Bluetooth technology to connect laptop and cell phone. We can move videos, images, photos etc from  desktop computer or a laptop to our cell phones. In order to use Bluetooth technology to connect laptop and cell phone we need a laptop and a cell phone which support this technology. 
    If the laptop doesn't support it, we can use a USB Bluetooth dongle.  Just plug it into the USB port of the desktop computer or laptop. Leave the rest to Microsoft Windows. It will find the driver and install it itself.  If it is not supported, we can manually install it via the manufacturer's compact disk. Follow these simple steps in order to use Bluetooth technology to connect laptop and cell phone: (In this example, we are using Windows Vista.)
     Turn on the Bluetooth feature on your cell phone.
     Make this setting:  my Phone's visibility -> Shown to all on the cell phone.
    Open Bluetooth Devices by clicking on its icon in the Control Panel.
    OR
    Look for the Bluetooth driver in the Device Manager and double-click on its icon.
    Click on the Add button in Bluetooth Devices dialog box.
    Check the box for "My devices is set up and ready to be found" in the Add Bluetooth Device Wizard dialog box.
    Click on the Next button.
    This device wizard will display the name of the found Bluetooth device close by.
    Click on the device name that you would like to add and click on Next.
    Select "Let me choose my own key" or "Choose a passkey for me" and click on Next.
    It will now display the passkey. Key this into the cell phone. Now the laptop is initiating to install the Bluetooth device. (Click Yes as you see the prompt message on the cell phone to allow connection with the laptop.)
    Click on the Finish button to close the dialog box of Add Bluetooth Device Wizard.
    The Bluetooth device (the cell phone) is now displayed in Bluetooth Devices dialog box. Select the Bluetooth device and click on the Properties button.
    The Properties dialog box for the device will become visible. Choose the Services tab.
    Check the boxes for the services you want.
    In the end you can launch the items of the cell phone.  Transfer photos, videos etc to cell phone via Bluetooth technology.
    This method can also be used to connect laptop to Bluetooth devices like Bluetooth mouse, Bluetooth keyboard, Bluetooth headset, etc.
