部分软件默认在C盘占用了很大的磁盘. 将文件夹迁移到其他盘,原地留下软连接,软件启动的之后,会访问到迁移后的位置,不影响软件适合用

FolderMigrator().mainloop()运行命令
我的脚本名字叫 folder_migrator.py
python
python folder_migrator.py打包命令
python
python -m PyInstaller -F -w -n "磁盘迁移" folder_migrator.py使用
- 选择原文件夹和目标的文件夹,点击按扭之后,会弹窗进行确认
- 点击确认,会迁移文件并调用cmd的管理员命令进行创建连接,若是原文件夹的迁移需要管理员权限,启动软件的时候,
