自创：密码文件夹
password.bat 内容
@echo off
md password
cd password
for /L %%a in (1,1,3) do (
md %%a
cd %%a

md %%b
cd %%b
for /L %%c in (1,1,3) do (
md %%c
)
cd ..

cd ..

原本我想创建 0-9 的 10 层嵌套密码文件夹，一开始我的思路是回溯，然后我把 C 语言的方法都写好了，转到 bat 时发现 batch 的函数根本没有 return，也就不能执行回溯；于是我干脆改成最简单的 9 层 for 循环，但当我一开始运行，就报错 The filename or extension is too long. 和 The system cannot find the path specified.，然后我算了一下，发现如果命令执行，总共要创建的文件夹的数量为：10^10 + 10^9 +...10^2 + 10，尼玛这就是天文数字啊，之后我删掉错误溢出的文件，显示正在删除文件，共 2207 个项目，预计耗时 5 分钟... 算了我还是改成 1-3 的 3 层嵌套密码文件夹吧，完。

补充：在原有的功能上进行了改进。不用手动修改日期，每次上传日记都会自动记录时间，并清空内容（只留下第一行的每周计划），但每天只能上传一次（判定条件是相同天只能上传一次），因此只需要第二天开机（或当天关机）时运行 Windows Terminal 即可，并且对以往的 .\up.bat 命令也进行了改进，变成了简洁的 up，这是因为在 Path 中记录了日记文件夹的位置，并且创建了快捷方式
