工具介绍

工具背景

你知道为啥我今天突然写这个吗？

我昨天下载视频，发现他全部都是分文件夹存的，一个一个开太麻烦了呢，今天就写了这个哈哈哈，全部拿出来，一下子就能全部添加到播放列表了！

只拷贝指定文件后缀的东西到新的文件夹里面，不管你原来的文件夹里面都多少个子文件夹都能给你把需要的文件复制出来（但是不会复制子文件夹，即不会复制原来的存储结构，我特意这么做的）！

你上次选的这四个选项，他会记住，后面再打开就是上次的位置。

4个文件介绍

CopyTheSpecifiedSuffixFiles.exe.config

相信你一眼就能看出来这个是干什么的了，没错！这个是这个软件的默认配置，当然你也可以在DataSave.txt中改动。

DataSave.txt

一开始是没有的，后面自动生成的哦~

拷贝的存储方式

1. 保留原文件（保留目标文件夹的重名文件）

2. 替换文件（替换目标文件夹的重名文件）

3. 保留并自动增加文件名称（拷贝的时候，后面会在后面加上_1区分，如下图）

只拷贝指定文件后缀的东西到新的文件夹里面，不管你原来的文件夹里面都多少个子文件夹都能给你把需要的文件复制出来（但是不会复制子文件夹，即不会复制原来的存储结构，我特意这么做的）！（重要的事情说两遍！为啥不说三遍？哈哈哈因为没有因为 0.o）

文件夹介绍

源文件夹

目标文件夹

结果

**使用 *.mp4**

使用 .

重名时坚持拷贝

可能的报错

因为你缺失这个东西，下载下就行了，一个底层的小玩意儿

C#代码如下

不想一点点弄可以直接下载上传的资源。
