在哪里放公共可写应用程序文件？ [英] Where to put common writable application files?
问题描述
我认为 CSIDL_COMMON_APPDATA\company\product 应该是放置应用程序的所有用户通用的文件，并且应用程序可以修改的位置，在Vista这是一个只读位置，除非由安装程序修改（根据MSDN - http://msdn.microsoft.com/en-us/library/ms995853.aspx ），所以...什么是最好的？修改位置的安全设置以允许写入或使用 CSIDL_COMMON_DOCUMENTS\company\product ？
>解决方案
只修改AppData目录的特定子目录上的安全性（这是从您提供的链接）：
CSIDL_COMMON_APPDATA此文件夹
应用于应用程序数据
，不是用户特定的。对于
示例，应用程序可以存储
拼写检查字典，
剪贴画的数据库或
CSIDL_COMMON_APPDATA文件夹中的日志文件。这个
信息不会漫游，对于使用
计算机的任何人都可以使用
。默认情况下，此位置对于普通（非管理员，
非电源）用户为
只读。 如果应用程序
需要普通用户写入
访问CSIDL_COMMON_APPDATA，
的应用程序特定的
子目录，则应用程序必须显式
修改安全性在应用程序
设置期间
子目录。修改的安全性必须是在供应商
调查表中记录的
。
I thought that CSIDL_COMMON_APPDATA\company\product should be the place to put files that are common for all users of the application and that the application can modify, however, on Vista this is a read-only location, unless modified by the installer (as per MSDN - http://msdn.microsoft.com/en-us/library/ms995853.aspx), so... what's best? Modify the location's security settings to allow writing or use CSIDL_COMMON_DOCUMENTS\company\product instead? Maybe there's a third option?
Also, is there an "official" Microsoft recommendation on this somewhere?
Modify just the security on a specific sub-directory of the AppData directory (this is from the link you provided):
CSIDL_COMMON_APPDATA This folder should be used for application data that is not user specific. For example, an application may store a spell check dictionary, a database of clip-art or a log file in the CSIDL_COMMON_APPDATA folder. This information will not roam and is available to anyone using the computer. By default, this location is read-only for normal (non-admin, non-power) Users. If an application requires normal Users to have write access to an application specific subdirectory of CSIDL_COMMON_APPDATA, then the application must explicitly modify the security on that sub-directory during application setup. The modified security must be documented in the Vendor Questionnaire.
