工程文件里面,除了代码,文档外,有很多垃圾文件,比如VC project里面的ncb,obj,pch等,要想备份文件夹,还得把它们剔出,特别麻烦.这个脚本我一直都用,可以把打包不同的文件夹,包括子目录,支持自定义保存的文件类型.
它会自动把备份文件压缩成zip格式

下载: pack.py

说明

  1. self.filter是一个字符串的列表,在里面定义需要备份的文件类型,只写不带分割符号的扩展名,大小写不敏感(windows平台上)
  2. 用法也很简单
    1. from pack import TBackup
    2. b=TBackup()
    3. b.SetSavePath('F:\\work_space\\back_up')
    5. b.addTask('F:\\work_space\\running\\tnl\', filter='F:\\work_space\\running\')
    6. #这个函数需要解释一下,两个参数,
    7. #第一个参数是需要备份的文件夹路径,
    8. #第二个参数filter,则是压缩文件里面的
    9. #参考路径,filter='F:\\work_space\\running\\"
    10. #备份成功之后,打开压缩包,会看到这样
    11. #的目录"".tnl",如果filter='F:\\work_space\\"
    12. #那么会看到"running\tnl"的目录
    13. b.run()
