How can I edit a SET variable in a batch file?

[senshi]

OK, I hope I can explain this well enough for some genius to understand and help me out

Im going to make a batch file that will be loaded by right-clicking mp3 files and selecting "some option" from the context menu.

Assuming I save this batch file as: C:\Windows\test.bat

Now, on right-clicking an mp3 file I will have an option that, if selected, will perform the following run command: "C:\Windows\test.bat" %1

The %1 automatically sets the selected mp3s filepath as a variable called %1 in the batch file.

So lets say I rightclick on C:\music\coolsong.mp3 and select "the option" from the menu... C:\Windows\test.bat will now load up and have the variable %1 which = "C:\music\coolsong.mp3"

Now here is what I want to do with this %1 variable:

I want to create a new variable with the selected mp3s directory path instead of the filepath. So for this example I will need to somehow set a variable which = "C:\music\"

I really don't know what to do. All I want is to take the variable I already have ("C:\music\coolsong.mp3") and transform it to: "C:\music\"

I really hope somebody here can help me out.

If anything, maybe someone here knows of a forum that I can join which specializes in topics about creating batch files?? It would really help me out.

Thanks alot everyone.

In your batch file, use this command:

@for %%F in (%1) do set New_Var_1=%%~dpF

This will set variable New_Var_1 as drive letter and path of %1.

For more information, check usenet newsgroup alt.msdos.batch, or the XP manual of the FOR command.

Hey I managed to figure it out with the help of someone on another forum.

Here is what needs to be done (for anyone interested):

for %%i in (%1) do echo %%~dpi

The above code will take the variable that has the complete filepath and echo the directory path only

Hey drBozo, you beat me to it by 1 min.

And yes, setting the new var does exactly what I need.

I appreciate the reply. Thanks for helping
