如何刪除指定天數前的文件以及指定天數以內文件大小大于指定數值的文件最后由 pcl_test 于 -4-10 12:15請教高手指點下，怎樣實現下面兩個的功能合并呢?1.文件自動刪除大于7天以上創建的文件rem 指定待刪除文件的存放路徑set SrcDir=D:DBrem 指定天數set DaysAgo=7>%temp%BackupDate.vbs echo Set WshShell = Wscript.CreateObject(Wscript.Shell)>>%temp%BackupDate.vbs echo Wscript.Echo WshShell.RegRead (HKEY_CURRENT_USERControl PanelInternationalsShortDate)for /f %%a in ('cscript /nologo %temp%BackupDate.vbs') do (set RegDateOld=%%a)>%temp%UnifyDate.vbs echo Set WshShell = Wscript.CreateObject(Wscript.Shell)>>%temp%UnifyDate.vbs echo WshShell.RegWrite HKEY_CURRENT_USERControl PanelInternationalsShortDate, yyyy-M-d, REG_SZcscript /nologo %temp%UnifyDate.vbs>%temp%DstDate.vbs echo LastDate=date()-%DaysAgo%>>%temp%DstDate.vbs echo FmtDate=right(year(LastDate),4) ^& right(0 ^& month(LastDate),2) ^& right(0 ^& day(LastDate),2)>>%temp%DstDate.vbs echo wscript.echo FmtDatefor /f %%a in ('cscript /nologo %temp%DstDate.vbs') do (set DstDate=%%a)set DstDate=%DstDate:~0,4%-%DstDate:~4,2%-%DstDate:~6,2%for /r %SrcDir% %%a in (*.*) do (if %%~ta leq %DstDate% (if exist %%a (del /f /q %%a)))>%temp%RecoverDate.vbs echo Set WshShell = Wscript.CreateObject(Wscript.Shell)>>%temp%RecoverDate.vbs echo WshShell.RegWrite HKEY_CURRENT_USERControl PanelInternationalsShortDate, %RegDateOld%, REG_SZcscript /nologo %temp%RecoverDate.vbsecho 7天前文件已刪除完成2.如果文件創建時間小于7天，則按文件創建時間先后刪除目錄里大于100GB以后的文件,只保留100GB謝謝各位高手
