upd:2025/10
- 初步完成了虚拟的文件夹及文件目录管理，主要功能有：创建虚拟文件夹、显示路径、创建文件、列出当前路径下文件（夹）、转到特定目录。
upd:2025/11/19
- 初步实现了与 \(\operatorname {windows}\) 的真实接口，现在可以真实地在该 \(\operatorname {exe}\) 下创建文件夹与文件。
upd:2025/11/20
- 我们实现了编辑文件和保存并退出。现存问题为：编辑文本的时候，文本量小时闪屏问题不严重，文本量超过1000后闪屏问题较为严重（模拟高频率输入时，若写小说等还好）。
upd:2025/11/21
upd:2025/11/24
- 准备了一个 \(\operatorname {4K}\) 小游戏，准备明天加入这个系统里面供游玩 ^_^。
