Search Only Changed Directory(s)

Question

See more:

I'm running this batch that works pretty good so far. The only downside is that it searches the entire hard drive everytime. I want to make it quicker. Is there a way that when it runs that it only checks the directory(s) that have changed since the last time it ran. I guess this means that the first time it runs it will check everything, unless it checks for directory(s) that changed today. Just throwing thoughts out there...any help is appreciated. Thanks

@echo off 
setlocal 
for /f "delims=" %%b in ("%time%") do set "tm=%%b" 
set "tm=%tm:~0,5%" 
set "tm=%tm: =0%" 


for /f "tokens=2" %%b in ("%date%") do set "d8=%%b" 


set filespec=\*.zip \*.txt \*.jpg 
for /f "delims=" %%a in (' 
dir %filespec% /a:-d /o:n /b /s') do ( 
if "%%~ta"=="%d8% %tm%" ( 
del "%%a"
) 
)

Unfortunately batch files have no memory.

For your use case it is better you did this in a higher level language which you can store information for your directories.

Ok. Thank you. Hey I was just wondering. You see in the code above I'm deleting just zip txt and jpg is there a way to add that to this? Meaning just delete zip txt or jpg instead of all? Thank you.

@echo off
cd "C:\Users\DS\Downloads"
setlocal
call :DateToMinutes %date:~-4% %date:~-10,2% %date:~-7,2% %time:~0,2% %time:~3,2% NowMins
for /f "delims=" %%a in ('dir * /a-d /b') do call :CheckMins "%%a" "%%~ta"
goto :EOF
:CheckMins
set File=%1
:set filespec=\*.zip \*.txt \*.jpg
set TimeStamp=%2
call :DateToMinutes %timestamp:~7,4% %timestamp:~1,2% %timestamp:~4,2% %timestamp:~12,2% %timestamp:~15,2%%timestamp:~18,1% FileMins
set /a MinsOld=%NowMins%-%FileMins%
if %MinsOld% leq 1 del %file%
goto :EOF
:DateToMinutes
setlocal
set yy=%1&set mm=%2&set dd=%3&set hh=%4&set nn=%5
if 1%yy% LSS 200 if 1%yy% LSS 170 (set yy=20%yy%) else (set yy=19%yy%)
set /a dd=100%dd%%%100,mm=100%mm%%%100
set /a z=14-mm,z/=12,y=yy+4800-z,m=mm+12*z-3,j=153*m+2
set /a j=j/5+dd+y*365+y/4-y/100+y/400-2472633
if 1%hh% LSS 20 set hh=0%hh%
if /i {%nn:~2,1%} EQU {p} if "%hh%" NEQ "12" set hh=1%hh%&set/a hh-=88
if /i {%nn:~2,1%} EQU {a} if "%hh%" EQU "12" set hh=00
if /i {%nn:~2,1%} GEQ {a} set nn=%nn:~0,2%
set /a hh=100%hh%%%100,nn=100%nn%%%100,j=j*1440+hh*60+nn
endlocal&set %6=%j%&goto :EOF
