Windows 7, 8用户在访问ProgramData目录和Documents and Settings目录时,会无法打开并被提示“C:\xxxx is not accessible. Access is denied.”因为权限不足而被拒绝访问。这是因为在Windows Vista以后的Windows操作系统中,默认的应用程序数据位置相对于使用广泛的Windows XP已经被修改了,而这几个目录之所以存在时为了兼容还试图访问它们的老程序。
它涉及了Documents and Settings和ProgramData下的所有文件,其中包括配置目录,缓存目录等等。
你完全不需要去使用某些工具或命令来获取这些目录的访问权限,因为我们可以很方便地去它们对应的路径来访问它们。
在Windows XP下默认保存用户数据(我的文档,我的音乐等)和应用程序配置,应用程序数据(Local Settings,Application Data等)被放在“Documents and Settings”目录下,自Windows Vista开始,包括Windows 7,Windows 8, Windows 8.1 以及还未正式发布的Windows 10,微软对这个目录结构左右一定的优化(简化目录名称并去除空格,减小目录深度,调整部分内容的划分方式),使之更加易用和合理。
大体上,是讲它们转移到了C:\User目录下。我在后面会给出完整的列表。
可能比较常用的是:
站在开发者的角度上“数据”和“配置”的划分有时候会比较模糊,但是变为“本地数据”和“可漫游数据”就好理解的多了。简单的说:假设一个有网络同步功能的RPG游戏,我分别在两台配置不同的机器上玩,不同机器我配置了不同的画面特效级别,它们就是只作用于本地的配置文件,而我的游戏进度则是应该漫游在各个机器上的数据。
为了兼容性考虑,微软还保留了名为ProgramData,Documents and Settings等的几个Junction Point(类似Linux的硬链接,没有接触过这个概念的朋友就当做是快捷方式好了),但是由于目录的替换是完整的一一映射(用户可以按照新方式找到所有文件),而且从微软的角度也不希望用户在去使用旧的划分方式,所以微软将默认情况下将它们的read权限设置为Everyone - Deny.
