对不起，它已经变得有点长。比较日期/时间只得到部分现在测试，但应该工作。小心，当它含有亚秒级，因为那些在这里介绍一个逗号扰乱参数顺序调用的子程序（因此％的时间的时候，：〜0，-3％避免）。

之后，你可以使用％〜TI 扩张来获得一个日期和时间，把它们比作当前减去一小时，如果适用删除。

注1：我假设ISO 24小时，这是我在这里使用8601日期和时间格式。对于非标准的日期格式，你将不得不改变一个子程序位（但12小时制时间可能会是一个痛苦）。

注2：code不关心闰年，目前。将是另一个5或6号线code的：one_hour_before ，我觉得

。

Exact Duplicates:

I have a folder named 'dump' on a sever on a network. Every day lot of temp files and folders will be saved in that folder.

I want to delete those files and sub folders. The condition is that I want to delete one hour before files & folders only i.e one our before the current time when we are running the batch file.

This means I want to keep one our files in that folder to run the other ACTIVITIES. like this current time.

go to folder and list the files as time wise
get the current time
delete the files which were 1 hour older than current time

解决方案

I think you are better off using PowerShell or WSH (as Rihan Meij mentioned) in this case. Comparing data and time is possible but very brittle (as there is no way to get a data/time in batch culturally-neutral). You might write something like this:

setlocal enableextensions
set Now=%date%
set NowTime=%time:~0,-3%
call :tokenize_date %Now%
call :tokenize_time %NowTime%
echo %YEAR%-%MONTH%-%DAY%T%HOUR%:%MINUTE%:%SECOND%
call :one_hour_before %Now% %NowTime%
echo %RESULT_DATE% %RESULT_TIME%
ping -n 1 -w 1500 ::1>NUL
set Now2=%date%
set NowTime2=%time:~0,-3%
call :date_time_compare %Now% %NowTime% %Now2% %NowTime2%
echo %Now%T%NowTime% compared to %Now2%T%NowTime2%: %RESULT%
endlocal
goto :eof

:tokenize_date
    rem assuming ISO 8601 date format YYYY-MM-DD
    setlocal enableextensions
    set arg=%1
    set YEAR=%arg:~0,4%
    set MONTH=%arg:~5,2%
    set DAY=%arg:~8,2%
    endlocal&set YEAR=%YEAR%&set MONTH=%MONTH%&set DAY=%DAY%
goto :eof

:tokenize_time
    rem assuming ISO-8601 time format HH:MM:SS, 24-hour
    setlocal enableextensions
    set arg=%1
    set HOUR=%arg:~0,2%
    set MINUTE=%arg:~3,2%
    set SECOND=%arg:~6,2%
    endlocal&set HOUR=%HOUR%&set MINUTE=%MINUTE%&set SECOND=%SECOND%

        set /a i+=1
        set month_length_!i!=%%x
    )

            set /a DAY+=month_length_!MONTH!
        )
    )
    endlocal&set RESULT_DATE=%YEAR%-%MONTH%-%DAY%&set RESULT_TIME=%HOUR%:%MINUTE%:%SECOND%
goto :eof

    rem expects %1 - date 1, %2 - time 1, %3 - date 2, %4 - time 2

                endlocal&set RESULT=-1&goto :eof
            ) else (
                if %MONTH2%%DAY2%%HOUR2%%MINUTE2%%SECOND2%==%MONTH%%DAY%%HOUR%%MINUTE%%SECOND% (
                    endlocal&set RESULT=0&goto :eof
                ) else (
                    endlocal&set RESULT=1&goto :eof

Sorry, it has gotten a bit long. Comparing date/time has only partially been tested right now, but should work. Careful with the time when it contains sub-seconds, since those introduce a comma here, which disturbs the argument order for called subroutines (hence the %time:~0,-3% to avoid that).

After that you can use the %~tI expansion to get a date and a time, compare them to current minus one hour and delete if applicable.

Note 1: I am assuming ISO 8601 date and time formats with 24 hours, which is what I am using here. For non-standard date formats you would have to alter the subroutines a bit (but 12 hour time would probably be a pain).

Note 2: The code doesn't care about leap years, currently. Would be another 5 or 6 lines of code in :one_hour_before, I think.
