Change drive letter using command line

If you are scared using command line changing drive letter can be done via GUI using the disk management tools interface.

If you are command line junkie, in Windows 7 or Windows 8 to change drive letter using command line is quite straight forward as well.

And one advantage of using command line if you need to change one or more computers, you don't need to disturb the user or visit the workstation.

Scripting using command line will automate the process.

To change using command line, open an elevated command prompt and type: diskpart

On diskpart window, type:

list volume and press enter

List volume will show all the volume available on the computer.

Select the volume you wish to change the drive letter.

Select volume 0 and press enter

Above command will select volume 0.

To changed drive letter of volume 0. Type this command:

Assign Letter=B and press enter

Assign letter=b, is quite straight forward command. It will assign the specified letter to the currently selected volume.

Type: exit and press enter.

Diskpart will be exited and open explorer; you will notice that volume 0 letter has been changed to drive B.

See image below, on my system which I run this command.

Volume 0 refers to the DVD drive; it could be different on your system.

That's it three command lines is needed on diskpart to change the drive letter.

1. List volume -- to list all volumes on the computer
2. Select volume #number -- select the desired volume number from the output of list volume
3. Assign Letter=Drive_Letter -- assign a value or drive letter for the selected volume

Cheers..Hope it helps..

Copy a single file using robocopy

Copy a single file using robocopy from a local folder to a shared folder on the network.
A simple rule of thumb before any disaster strike, don't interchange the source and the destination.

If source and destination is mistakenly reverse, files might get overwritten. To avoid any loss of data do a test with a dummy file to ensure things work perfectly.
Robocopy [source][destination]   [file to be copied]
robocopy c:\local_c_folder  \\PC_network\shared_folder   file_to_be_copied_xx.txt
The command will be completed successfully provided the network access right has no issues.

Robocopy works quite good on large files. A simple copy or xcopy command will also work but the speed might vary.

However, if the file (ex. an ISO file) and is more than 4GB and the filesystem  of the thumbdrive or the storage is FAT system, then robocopy or any methods of copying will not work. Since FAT has a file size limitation of less than 3GB.

Robocopy is free it can be accessed from command line. No ne…
