问题 My application is something similar to a Contact Manager. Let's say a user can enter contacts with their addresses. I have the code and technology to save my contacts to a file.

阅读更多关于 Where to put common writable application files?

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?

Use SHGetFolderPath with CSIDL_COMMON_APPDATA as the CSIDL.

阅读更多关于 How do I find the Windows common application data folder using Python?

I would like my application to store some data for access by all users. Using Python, how can I find where the data should go? If you don't want to add a dependency for a third-party module like winpaths, I would recommend using the environment variables already available in Windows: What environment variables are available in Windows? Specifically you probably want ALLUSERSPROFILE to get the location of the common user profile folder, which is where the Application Data directory resides. e.g.: C:\> python -c "import os; print os.environ['ALLUSERSPROFILE']" C:\Documents and Settings\All Users

SHGetFolderPath() for a specific user

问题 I'm looking for a good way to get the local application data folder for a specific user -- without having to enter the login details for that user. SHGetFolderPath() can accept an access token for whatever user I want to get the local appdata folder for, but to get an access token, you have to provide the user's password.
