问题
I need to write to the:
C:\Users\user\AppData\Roaming\AppName
folder during the setup process. I'm using the InnoIDE program for setup, and it's awesome. However, it seems to be lacking an 'AppData' special folder for easily accessing that directory.
For example, you can use:
DestDir: "{app}"
to write the application directory.
But how do you get to AppData? Is there a list of all the preset DestDir options?
回答1:
Arg, got it.
{userappdata} → C:\Users\user\AppData\Roaming\AppName
as found here: http://news.jrsoftware.org/news/innosetup/msg74694.html
回答2:
As you said in your own answer, {userappdata} is the one you need. The help manual has a list of all the Inno Setup directory constants.
回答3:
It is not recommend to write to AppData directory using InnoIDE. You better save user-specific data to a shared location first (e.g. under {app}) and have your application copy it from there on first startup.
