Batch File: How to delete files sort by date if there are subfolders in the folder? -

here 1 example:

there 4 files:

c:\test\1002.bak -- created on oct 2nd,2014 c:\test\1009.bak -- created on oct 9th,2014 c:\test\subfolder\1001.bak -- created on oct 1st,2014 c:\test\subfolder\1008.bak -- created on oct 8th,2014

i want batch file delete older files sorted date, files including subfolders.

it should sorted like:

c:\test\subfolder\1001.bak c:\test\1002.bak c:\test\subfolder\1008.bak c:\test\1009.bak

but if run below command, result has been separated subfolder. instance, "dir /a-d /od /s > result.txt"

result.txt:

volume in drive c has no label. volume serial number aadb-db05 directory of c:\test 2014/10/02 11:40 4,220,416 1002.bak 2014/10/09 07:02 1,453,321,216 1009.bak 2014/10/09 18:44 0 result.txt 3 file(s) 1,457,541,632 bytes directory of c:\test\subfolder 2014/10/01 10:51 4,220,416 1001.bak 2014/10/08 07:02 1,418,283,008 1008.bak 2 file(s) 1,422,503,424 bytes total files listed: 5 file(s) 2,880,045,056 bytes 0 dir(s) 35,598,852,096 bytes free

"dir /a-d /od /s /b> result.txt"

result.txt:

c:\test\1002.bak c:\test\1009.bak c:\test\result.txt c:\test\subfolder\1001.bak c:\test\subfolder\1008.bak

is possible sort files including subfolders date , remove older files when folder disk size reach limitation? give thanks help.

@echo off set "targetfolder=%cd%" /f "skip=4 tokens=2,*" %%a in (' robocopy "%targetfolder%" "%targetfolder%" /l /nocopy /is /s /njh /njs /ndl /nc /ns /ts ^| sort /r ') echo del "%%b"

this code uses robocopy command (native in windows vista , later versions, available download previous versions) not re-create files, list of files timestamp in yyyy/mm/dd hh:nn:ss format. list sorted in descending order (sort /r) , first (newer) files in list skipped (skip=4). remaining elements in list del command executed.

del operations echoed console. if output correct, remove echo command
