changing directory folder to all sub folders - batch-file

Question

Hello i have a batch script but i cant work out how to change the path to scan all subfolders within the directory.
In other words i dont want -
C:\Users\ally\Desktop\Documents\Table\CSV versions\2014\
but rather:
C:\Users\ally\Desktop\Documents\Table\CSV versions
as there are lots of different years of data in seperate folders.
Also to note within year folder there are month folders and within that there are the csv files.
#echo off
setlocal enabledelayedexpansion
set "target=C:\Users\ally\Desktop\Documents\All"
cd /d "C:\Users\ally\Desktop\Documents\Table\CSV versions\2014\"
for /L %%a in (101,1,148) do (
set num=%%a
del "%target%\-!num:~-2!.csv" 2>nul
>"%target%\-!num:~-2!.csv.txt" echo Type,angle,edge,Date,Frame,Sum,Mafe,Comp,Rim,Dose,Ell,Role
)
for %%a in (*.csv) do (
for /f "skip=1 usebackq delims=" %%b in ("%%a") do (
for /f "tokens=1,2 delims=-," %%c in ("%%b") do (
set "line=%%c"
if /i "!line:~0,2!"=="HH" >> "%target%\-%%d.csv.txt" echo %%b
)
)
)
ren "%target%\*.csv.txt" *.
pause

To process every folder under the All tree then you can use a for /d /r loop and pushd/popd to set the current folder.
This assumes that every folder has the files you want to process.
Test this on a copy of your data and change the folder to point to it.
You seem to be deleting .csv files, creating .csv.txt files and then trying to process *.csv in the lower loop. Should that be *.csv.txt ?
#echo off
setlocal enabledelayedexpansion
for /d /r "c:\Users\ally\Desktop\Documents\All" %%z in (*) do (
pushd "%%z"
for /L %%a in (101,1,148) do (
set num=%%a
del "-!num:~-2!.csv" 2>nul
>"-!num:~-2!.csv.txt" echo Type,angle,edge,Date,Frame,Sum,Mafe,Comp,Rim,Dose,Ell,Role
)
for %%a in (*.csv) do (
for /f "skip=1 usebackq delims=" %%b in ("%%a") do (
for /f "tokens=1,2 delims=-," %%c in ("%%b") do (
set "line=%%c"
if /i "!line:~0,2!"=="HH" >> "-%%d.csv.txt" echo %%b
)
)
)
ren "*.csv.txt" *.
popd
)
pause

Try adding another loop that will walk down the directory tree and if it finds a csv file, it will process it:
#echo off
setlocal enabledelayedexpansion
set "target=C:\Users\ally\Desktop\Documents\All"
for /f "tokens=1* delims=" %%D in ('dir /s /b /o:-n /a:d "C:\Users\ally\Desktop\Documents\Table\CSV versions"') do (
cd /d "%%~fD"
if exist *.csv (
for /L %%a in (101,1,148) do (
set num=%%a
del "%target%\-!num:~-2!.csv" 2>nul
>"%target%\-!num:~-2!.csv.txt" echo Type,angle,edge,Date,Frame,Sum,Mafe,Comp,Rim,Dose,Ell,Role
)
for %%a in (*.csv) do (
for /f "skip=1 usebackq delims=" %%b in ("%%a") do (
for /f "tokens=1,2 delims=-," %%c in ("%%b") do (
set "line=%%c"
if /i "!line:~0,2!"=="HH" >> "%target%\-%%d.csv.txt" echo %%b
)
)
)
ren "%target%\*.csv.txt" *.
)
)

Explanation of the dir switches:
/s - Displays files in specified directory and all subdirectories.
/b - Uses bare format (no heading information or summary).
/o:in - Lists the files in reverse order
/a:d - Displays only folders
Explanation of the %%~fD: expands %A to a fully qualified path name (from for /?)
