I need a Windows batch code to find the last modified file among all the files in all the subfolders of a specific folder.
It doesn't seem to be so simple as it appears.
Some files could have been modified in the same minute, but in different seconds. I need only the lastest one.
@echo on
setlocal enableextensions disabledelayedexpansion
set "root=c:\somewhere"
for %%r in ("%root%\.") do for /f "tokens=3,*" %%a in ('
robocopy "%%~fr." "%%~fr." /l /nocopy /s /is /njh /njs /ndl /nc /ns /ts
^| sort /r
^| findstr /n "^"
^| findstr /l /b /c:"1:"
') do echo %%b
This code uses robocopy (native for Vista and later OS versions, downloadable from Microsoft for XP or 2003) to obtain a list of files with timestamp in yyyy-mm-dd hh:nn:ss format, that is sorted in decreasing order and then only the first line (that is, the newer file) is retrieved.
