Store randomized folder in a batch script? - windows

Question

I have a script that automatically backup NAPS2 (Scanner program) newest scan result to another drive, and also rename it according its timestamp...
Problem is, NAPS2 uses randomized folder name as the parentfolder of its scan result... e.g
"C:\Users\username\AppData\Roaming\NAPS2\recovery\4j4v.fbmv\scanresult001.jpg"
Here's the code, how do i point to that randomized folder?
SET ROOTDIR=C:\Users\Operator\AppData\Roaming\NAPS2\recovery\
for /f %%i in ('dir %ROOTDIR% /b /AD /od /t:w') do set LATEST_DIR=%%i >NUL
SET RANDOMDIR=%ROOTDIR%%LATEST_DIR%
for /F "delims=" %%a in ('dir /b /od "%RANDOMDIR%\*.jpg"') do set Youngest=%%a
echo Backing up %Youngest%
for /f "delims=" %%a in ('wmic OS Get localdatetime ^| find "."') do set dt=%%a
set YYYY=%dt:~0,4%
set MM=%dt:~4,2%
set DD=%dt:~6,2%
set HH=%dt:~8,2%
set Min=%dt:~10,2%
set Sec=%dt:~12,2%
set mydate=%YYYY%%MM%%DD%#%HH%%Min%%Sec%
copy "%Youngest%" "D:\Backup\%mydate%.jpg"
Output
C:\>for /F "delims=" %a in ('dir /b /od "C:\Users\Operator\AppData\Roaming\NAPS2
\recovery\jfwkui0s.pmd \*.jpg"') do set Youngest=%a
File Not Found
C:\>echo Backing up
Backing up
C:\>for /F "delims=" %a in ('wmic OS Get localdatetime | find "."') do set dt=%a
:\>set dt=20160818125756.950000+420
C:\>set YYYY=2016
C:\>set MM=08
C:\>set DD=18
C:\>set HH=12
C:\>set Min=57
C:\>set Sec=56
C:\>set mydate=20160818#125756
C:\>copy "" "D:\Backup\20160818#125756.jpg"
The system cannot find the path specified.
I think it's probably because the randomized folder has "." in it.. I tried "New Folder" which has space in it and it doesnt work as well

To do this use the approach shown in https://stackoverflow.com/a/30311479/6550457
You'll want to do it only for directories though so instead of a-d use ad
SET ROOTDIR=C:\Users\username\AppData\Roaming\NAPS2\recovery\
for /f %%i in ('dir %ROOTDIR% /b /AD /od /t:w') do set LATEST_DIR=%%i>NUL
echo Latest Dir = %LATEST_DIR%
so in your script you'd use it as:
SET ROOTDIR=C:\Users\username\AppData\Roaming\NAPS2\recovery\
for /f %%i in ('dir %ROOTDIR% /b /AD /od /t:w') do set LATEST_DIR=%%i>NUL
SET RANDOMDIR=%ROOTDIR%%LATEST_DIR%
echo Backing up %RANDOMDIR%
for /f "delims=" %%a in ('wmic OS Get localdatetime ^| find "."') do set dt=%%a
set YYYY=%dt:~0,4%
set MM=%dt:~4,2%
set DD=%dt:~6,2%
set HH=%dt:~8,2%
set Min=%dt:~10,2%
set Sec=%dt:~12,2%
set mydate=%YYYY%%MM%%DD%#%HH%%Min%%Sec%
copy "%RANDOMDIR%" "E:\Backup\%mydate%.png"
