When an external drive is used on Windows it is not guaranteed to be assigned the same drive letter as the last time it was used.
That makes it awkward if you're running a batch file that depends on a certain drive being attached, such as when doing backups, without having to change the drive letter used in the batch file. Luckily there are several utility commands that return the volume name for a disk drive, among them is Vol and another is the more sophisticated Windows Management Instrumentation Command-line WMIC. Vol returns the volume information of a given drive letter. Attaching my backup external drive, which as the volume label "Backup1" to the computer I can see in Explorer that the drive letter is H:.
Knowing what the text returned from the utility is, it should be fairly simple to parse it using Find and return the label information. We'll need to check all possible drive letters. What the above batch file does is loop through every letter then uses Find to check the text returned from Vol for the volume name. If it finds it then it sets a variable called MyDrive to the drive letter found to match the volume name. The system cannot find the path specified. The device is not ready. Drive letter is h: Press any key to continue.
Let's see if we can get rid of the system messages. We can use it to replace the errorlevel test line. Wouldn't it be nice if there was some way we could just test the attached drives and not have to go through the entire alphabet? Windows does have a couple of utilities that can do this. One is using the Fsinfo subset of Fsutil. On my computer, the command. The problem is that Fsutil requires that it be run as an administrator, which is not suitable for all occasions.
For more specific information on Fsutil Fsinfo see Microsoft Technet. Another command that can get a computers drive letters is Mountvol. Mountvol is used to creates, delete, or list a volume mount point.
If used without any parameters it will list the computers drives. VolumeName Specifies the volume name that is the target of the mount point. You can make the volume mountable again by creating a volume mount point. The output of this can be parsed using Find for just the drive letters and those passed to the Vol command to find and match the volume labels. This means the batch file should be more efficient as it does not have to check every drive letter, just the ones that Mountvol reports as being attached.
Basically it is telling the command processor that the pipe character is a pipe character and not plain text. Is there a way without having to parse one utility and passing the output to Find then pass the result of that to Vol?
I don't think we can do without the parsing part using find, because I do not know of a utility that returns the drive letter when the volume label is entered. If there was then we wouldn't be writing this batch file. Notice in the second form the drives are listed alphabetically and include drive Z: which is a network drive on my system. For some tasks multiple external drives may be needed.
The following batch file uses a For loop to test for the drives in the list and will give an error message if any are not present. The Find utility is used in many of these batch files to find text in the output of other programs such as Vol and Mountvol.
Care must be taken that the volume label of the drive you are looking for us not one of the words in the output of these programs. The volume names must be unique. For example if Find is used to find "back" it will also find "backup.

FOR Runs a specified command for each file in a set of files. IF Performs conditional processing in batch programs. MD Creates a directory. MODE Configures a system device. MORE Displays output one screen at a time.In this tutorial, you will learn about batch file commands and how they are used in batch file scripting or programming. It has extension of. Click here to go through the introduction of the batch file before learning batch file commands.
For the ease of learning, we have listed all the batch file commands with relevant examples and explanations below. Please click on the commands to know the details. If only ASSOC is written and executed, it will display all the file associations for every extension, instead of just.
The batch command ATTRIB is used to display the file attributes or set an attribute to a file in the working directory. Now let us suppose we have a file note.
How to Find a Drive's Volume Label or Serial Number
We will display its file attributes and then make it hidden and read only by adding 'ah' and 'r' attributes to it. And finally, we will remove some attributes we added as well. The batch command COMP compares the size of two files and checks if they are different in size.
This script will ask for users permission to check the properties of disk partition and if allowed, will display following output in the console depending on disk properties. This output shows the fraction of drivers list with their properties and installed date.
Besides printing message, echo is also used for deciding whether or not to display the command itself. Like in this example as well, in the first line we have turned OFF echo, which makes sure that commands themselves are not printed. In this example, as soon as HI is printed in the console, EXIT command will terminate the program and close the output console. This script will extract all the contents of xyz. The batch command FC finds the difference between the two files and displays them to console.
The batch command FIND search the given file to find the desired string and if located, it displays the corresponding line in which the string exists. This might be the one of the most important batch file commands because with this HELP command we can know about all the other commands used in batch file or command prompt.
Now that we have a list of batch file commands, we can also view details of their syntax and functionalities in following way:. The batch command LABEL displays the label of a drive or volume and is also is used for adding, setting or removing a disk label.
To make the Batch file "ask for a volume", execute: sndvol. There is no way that a Batch file "set the volume" via standard commands, but a third party program can do it, like NirCmd. Learn more.
Asked 6 years, 1 month ago. Active 4 years, 4 months ago. Viewed 10k times. I am making a batch-file that will start a song and i want to make it ask for a volume.
How do I set the volume? Is it even possible? Alex Alex 5 5 silver badges 8 8 bronze badges. I start it with the start-command. I know how to do that but how do i change the volume on my computer?
You start it with start whateverutilty. There might be some parameters to the utility to set the volume. You will find them in the documentation of the utiltiy.

Batch - Running Diskpart from batch file. Samuel-AMC asked. Medium Priority. Last Modified: Hello everyone, "Batch Diskpart, running few commands at the same time. For example, this is what i do when ever i use Diskpart and few commands: 1.
I open CMD, and type: Diskpart 2. Then type: List volume, or depending on what i want Diskpart to do for me. Then i keep doing this line per line, etc.
But thats what i would like to be able to do, but all my attempts have failed. Any help will be very appreciate, Thanks in advance. Start Free Trial. View Solution Only.

Commented: Sumesh BNR. Author Commented: Thanks Qlemo, sumeshbnr, Let me explain a little bit more, one of the thing i use Diskpart the most, is to remove drive from my computer window, and i tried before what Qlemo suggested, and never worked for me, but let me try again with your example.
Now i need to figured out how to do the task, if i add the code you posted, it runs, but then close very fast, so i added a pause at the end, now i can see diskpart working.The cd command, also known as chdir ch ange dir ectoryis a command-line shell command used to change the current working directory in various operating systems. It can be used in shell scripts and batch files.
This is the case in most of the Unix shells Bourne shelltcshbashetc. The system call that effects the command in most operating systems is chdir that is defined by POSIX. This means that when the command is executed, no new process is created to migrate to the other directory as is the case with other commands such as ls.
Instead, the shell itself executes this command. This is because, when a new process is created, child process inherits the directory in which the parent process was created.
If the cd command inherits the parent process' directory, then the objective of the command cd will never be achieved. Windows PowerShellMicrosoft's object-oriented command line shell and scripting languageexecutes the cd command cmdlet within the shell's process. However, since PowerShell is based on the. NET Framework and has a different architecture than previous shells, all of PowerShell's cmdlets like lsrm etc. Of course, this is not true for legacy commands which still run in a separate process.
A directory is a logical section of a file system used to hold files. Directories may also contain other directories. The cd command can be used to change into a subdirectory, move back into the parent directory, move all the way back to the root directory or move to any given directory.
A similar session in DOS though the concept of a "home directory" may not apply, depending on the specific version [ vague ] would look like this:.
DOS maintains separate working directories for each lettered driveand also has the concept of a current working drive. The cd command can be used to change the working directory of the working drive or another lettered drive. Typing the drive letter as a command on its own changes the working drive, e. Modern versions of Windows simulate this behaviour for backwards compatibility under CMD.
Note that executing cd from the command line with no arguments has different effects in different operating systems. If cd is executed without arguments in Unix, the user is returned to the home directory. Executing the cd command within a script or batch file also has different effects in different operating systems.
In DOS, the caller's current directory can be directly altered by the batch file 's use of this command. In Unixthe caller's current directory is not altered by the script's invocation of the cd command. This is because in Unix, the script is usually executed within a subshell. In the File Transfer Protocolthe respective command is spelled CWD in the control stream, but is available as cd in most client command-line programs.
Some clients also have the lcd for changing the working directory l ocally. From Wikipedia, the free encyclopedia. Free and open-source software portal. Microsoft Press. Retrieved Unix command-line interface programs and shell builtins.Link volumes without requiring a drive letter. Create, delete or list a volume mount point. VolumeName : The volume name that is the target of the mount point. The GUID is used to identify a unique volume even if the drive letter changes.
If other processes are using the volume, mountvol closes any open handles before dismounting the volume. You can make the basic volume mountable again by assigning a volume mount point. If you need to expand your volume space without reformatting or replacing a hard drive, you can add a mount path to another volume.
The benefit of using one volume with several mount paths is that you can access all local volumes by using a single drive letter such as C:. You do not need to remember which volume corresponds to which drive letter—although you can still mount local volumes and assign them drive letters.
These utilities affect the target directory and all subdirectories. List a brief help text followed by a list of the volumes, mount points and GUIDs on your system:. Equivalent bash command Linux : mount - Mount a file system.
