It is not okay to use the task scheduler to run the delete command every 100 days, because the LZ requires deleting files that are 100 days ago, not deleting files every 100 days. The difference between these should be very obvious, right? For example: A file created on the 99th day should be deleted on the 199th day. If you don't calculate and judge, and directly kill everything every 100 days, a file created on the 99th day will be deleted the next day.

Everyone thinks there should be code execution, and the thinking is a bit rigid. The brother on the 13th floor is very good.

For example, to delete the files under the D:\C1 folder. Using the forfiles that comes with Microsoft Windows 2003 is really a tenth of the effort but a hundred times the result. forfiles /p D:\C1 /d -100 /c "cmd /c del @file" [ Last edited by aspirer on 2007-1-20 at 10:32 PM ]

The understanding of building 13 is incorrect, but the idea is good. The idea of building 20 is also not bad. But it only runs under 2003.
