Where should a IE browser helper object store its data files?

Question

I'm writing a browser helper object for internet explorer that needs to store some data on the hard disk. Is there a convention, where to store this files? Or if not - to which directory (except the temp folder) do I have write access?

Answer 1

Normally applications store state in CSIDL_LOCAL_APPDATA or CSIDL_APPDATA but a low IL process (like Protected IE ) cannot write to those directories, for low IL you can use FOLDERID_LocalAppDataLow .

When running inside the IE process you can use special IE versions of those APIs: IEGetWriteableFolderPath and IEGetWriteableHKCU

Answer 2

在IEGetWritableFolderPath（）返回的路径下为您的应用创建子目录。
