Relative file path in Batch

M

I'm trying to write a batch file to run a command line on all of the files in a directory structure and copy the resulting outputs to the same structure but at an alternate root

ie
batch file located at c:\one\two
file to process located at c:\one\two\three\four\five.extension
I want to move the output file five.extension2 now located at c:\one\two\three\four
to new location %NEW_PATH%\three\four

~dp0 will give me the batch path (c:\one\two)
~f will give me the full file path for five.extension (c:\one\two\three\four\five.extension)
~n gives the file name I care about (five)
but I can't seem to find a way to parse out the "\three\four" for the move command (%NEW_PATH%\three\four)

any help would be appreciated

I know this sounds rather dumb of me, maybe I'm just misinterpreting the question, but can't you just copy and paste the created batch file to the new location, sounds like a long way to go to move a file from one place to another, again correct me if you think I've misinterpreted the question

This will get put in a loop that recursively acts on all of the files in a structure so this will get run on 100s of files. And I was using copy as an example, its actually a video encode command line. IE, I want to convert all of my home movies into smaller files for posting on the web but keep the same sort of directory structure without polluting my home movies directory.

Hello and welcome to the Vista Forums!

You might be able to do it in a batch file, you certainly could in a Visual Basic Script, but I am not familiar with either, and it all seems a bit pointless.

I can see that you don't want to modify your original movies, but how about copying your entire library to a new copy (duplicate it) and then just allow the script to modify the (now duplicated) originals?

What I did was create a small function that got the length of the top level directory (ie C:\one\two) and used this to get the substring I needed out of %%~dpi (I assume you are going through it in a batch file loop like me where %%i is the current file). Then something like

set folder=%%~dpi
set folder=!folder:~%len%!

would get the relative file path you are after.

The string length function and rest of the code with comments on batch file string manipulation are here. (it's part of a larger script that compares file last-modified field before copying)
