how copy multiple files @ last modified?

for example, have files this. want copy file a.csv, b.csv, , c.csv folder 1 folder 2 , if possible, want delete previous data on folder 2 (d.csv, e.csv,and f.csv)

+--------------------------+  +--------------------------+ |       folder 1           |  |     folder 2 (before)    | +----------+---------------+  +----------+---------------+ |   name   | date modified |  |   name   | date modified | +----------+---------------+  +----------+---------------+ | a.csv    | 2017-07-26    |  | d.csv    | 2017-07-25    | | b.csv    | 2017-07-26    |  | e.csv    | 2017-07-25    | | c.csv    | 2017-07-26    |  | f.csv    | 2017-07-25    | | d.csv    | 2017-07-25    |  +----------+---------------+ | e.csv    | 2017-07-25    |      hope :) | f.csv    | 2017-07-25    |  +--------------------------+ | g.csv    | 2017-07-24    |  |     folder 2 (after)     | | h.csv    | 2017-07-24    |  +----------+---------------+ | i.csv    | 2017-07-24    |  |   name   | date modified | | .....    | ....-..-..    |  +----------+---------------+ +----------+---------------+  | a.csv    | 2017-07-26    |                               | b.csv    | 2017-07-26    |                               | c.csv    | 2017-07-26    |                               +----------+---------------+ 

:: remove .csv files destination del "%folder2%\*.csv" pushd "%folder1%" :: date lastdate latest date/time of file in folder1 /f "tokens=*" %%a in ('dir /b /a-d /o-d "*.csv"') set "lastdate=%%~ta"& goto next :next :: grab first 8 characters (may need 10, depending on date/time format) :: - date part set "lastdate=%lastdate:~0,8%" /f "tokens=*" %%a in ('dir /b /a-d /o-d "*.csv"') echo "%%~ta" | find "%lastdate%" >nul & if errorlevel 1 (  goto done  ) else (copy "%%~a" "%folder2%") ) :done popd 

so - first clear folder2, switch current directory folder1

set lastdate date/time string first .csv found in reverse-date order , remove time portion.

run through directory again , see whether date found in lastdate matches file's date. if does, errorlevel set 0, otherwise non-zero.

the if errorlevel test interprets current value of errorlevel, , evaluates true if value of errorlevel nominated value or greater, otherwise false, need copy file if errorlevel 0 (the date matches lastdate) , since files being listed in date-order, finding first non-match mean remaining files non-match on date, can exit thefor loop done , pop original directory.
