DOS- keeping portion of directory structure during xcopy? - batch-file

Question

I am a bit new to DOS batch files, and I am having a hard time wrapping my head around ways to solve my problem.
What I need to do: I have a large, nested source folder structure, let's say it lives here:
C:\dir1\dir2\dir3\file.txt
And I have a mirrored destination structure, although a portion of the root is different:
x:\dirA\dirB\dir1\dir2\dir3\file.txt
My current batch copies all files in the source structure to a destination folder, keeping the folder structure, which is what I want.
The problem:
The intention of my script is to drag a folder from the source structure above onto the bat file, and have it copy the files to the destination. What I want to do, is to allow the user to drag a folder from source dir, let's say /dir2 and all of its subfolders/files onto the batch file, and have it copy the contents over to the SAME spot in the destination structure...
So in this example, the batch file should copy everything in and below:
C:\dir1\dir2\
into
x:\dirA\dirB\dir1\dir2\.
Fortunately (I think) my destination folder structure won't be changing, although the source might be in a different location on each machine. So, if there is a clever way to detect where in the source tree I am, and then replace a portion of the destination path... ???
Here's my simple script so far:
#echo off
set /p FILETYPE="What file type do you want to copy? (For example use txt, max, f3d, or * to copy all files.)"
xcopy %1\*.%FILETYPE% c:\output /s
pause
Thanks so much for any help you guys can give! :)

UPDATE: Adding updated code sample here because I cannot get my comment to format or allow me enough chars. The stuff below may not be completely correct, I am just trying my best to be clear. I have figured out more since I posted this, basically I need to figur out how (or if possible) to use a string after delims, it only seems to check for each character...
#echo off
rem user drag folder onto .bat (left click, move folder using mouse onto .bat icon)
rem %1 in ex is C:\random_folder\another_folder\proj1\area1\scene23
set destRoot=X:\companyname\allprojects\proj1
set rootDir=proj1
rem assume %1 is folder dragged onto .bat file
for /f "tokens=2* delims=<foldername???>" %%a in ("%1") do (
set part1=%%a
set chunk=%%b
)
set finalDest=destRoot+chunk
xcopy %1\* %finalDest% /E /EXCLUDE:exclusions.txt
pause
I am hoping to create this: "X:\companyname\allprojects\proj1\area1\scene23"

Answer 1

Is the x:\dirA\dirB\ part of the destination folder known? If so, the solution is easy:
#echo off
rem Get current directory, ie: "C:\dir1\dir2"
set curDir=%cd%
rem Eliminate the disk drive, ie: "\dir1\dir2"
set curDir=%curDir:~2%
rem Copy to right destination, ie: "x:\dirA\dirB\dir1\dir2"
xcopy *.%FILETYPE% "x:\dirA\dirB%curDir%"
I hope it helps...
EDIT: Clarification to new comments requested
Ok. There is a source folder and a destination folder. The program above assume that the current folder for the program is source folder, but this may be provided as a parameter if needed. The program achieve the following copy processes:
From source folder -> To destination folder
C:\dir1\dir2 -> x:\dirA\dirB\dir1\dir2
C:\dir1\dir2\dir3 -> x:\dirA\dirB\dir1\dir2\dir3
C:\dir1\dir2\dir3\what\ever -> x:\dirA\dirB\dir1\dir2\dir3\what\ever
C:\XYZ -> x:\dirA\dirB\XYZ
If this is not what you want then explain it as concise as possible (use "files", "folder", "part of name" terms, not "I like", "what if", etc), and include three or four examples.
Also, note that for me drag a folder mean a drag&drop operation taking the source folder pressing the right button of the mouse and leave it over the icon of the Batch file. If you are NOT refering to this operation, please do NOT use "drag" term; use "copy" instead (please also clarify this point).
EDIT: Solution to new requirements
OK! You have not explained correctly before your last example! This problem is just about matching two names: last part of first name must match the same part in second name, and combine first name and the rest of second name. Right?:
First name: X:\companyname\allprojects\proj1
Second name: C:\random_folder\another_folder\proj1\area1\scene23
Result: X:\companyname\allprojects\proj1\area1\scene23
This is the solution:
#echo off
setlocal EnableDelayedExpansion
rem user drag folder onto .bat (left click, move folder using mouse onto .bat icon)
rem %1 in ex is C:\random_folder\another_folder\proj1\area1\scene23
set sourceFolder=%~1
set destRoot=X:\companyname\allprojects\proj1
rem Get last part of First name (destRoot) ie: lastPart=proj1
for %%a in (%destRoot%) do set lastPart=%%~Na
rem Delete from beginning of second name until that part, ie: result=\area1\scene23
set result=!sourceFolder:*%lastPart%=!
rem And insert the First name before the rest
set result=%destRoot%%result%
Or, combining the three steps in just one line:
#echo off
rem user drag folder onto .bat (left click, move folder using mouse onto .bat icon)
rem %1 in ex is C:\random_folder\another_folder\proj1\area1\scene23
set sourceFolder=%~1
set destRoot=X:\companyname\allprojects\proj1
for %%a in (%destRoot%) do set result=%destRoot%%sourceFolder:*%%~Na=%
Please note that if destRoot may contain spaces, it must be enclosed in quotes in the FOR command: for %%a in ("%destRoot%") do ...

Answer 2

Got this on another forum, seems to contain the answr I was looking for, sharing here for others:
#echo off
REM YOU NEED THIS
setlocal enabledelayedexpansion
REM If the passed parameter string has any spaces you must quote it
REM we unquote it using ~
set PassedString=%~1
REM May as well do the same with string to split on
set DelimString=%~2
REM The delim string must appear exactly ONCE in the passed string
REM Replace the delim string with a symbol which will not be in the
REM path to be split, in this example I use #
set splitsub=#
call set tempstring=!PassedString:%DelimString%=%splitsub%!
REM Use FOR to split the modified string
for /f "tokens=1* delims=%splitsub%" %%A in ("%tempstring%") do set part1=%%A & set part2=%%B
REM Show that the 2 variables contain the desired substrings
echo Passed = %PassedString%
echo Part1 = %part1%
echo Part2 = %part2%
Example output:
C:\>splitstring.bat "D:\Backup\mystuff\programming\Visual Basic\project\ABCDE\DEF" "project"
Passed = D:\Backup\mystuff\programming\Visual Basic\project\ABCDE\DEF
Part1 = D:\Backup\mystuff\programming\Visual Basic\
Part2 = \ABCDE\DEF
C:\>splitstring.bat "D:\Backup\mystuff\programming\Visual Basic\project\ABCDE\DEF" "mystuff"
Passed = D:\Backup\mystuff\programming\Visual Basic\project\ABCDE\DEF
Part1 = D:\Backup\
Part2 = \programming\Visual Basic\project\ABCDE\DEF
