The ##Attributes.ini file exists in the folder macros of the project folder and applies configuration settings at the directory level.
The Package.ini file applies settings at the overall application level. You can use the DirectoryIsolationMode, CompressionType, and ExcludePattern parameters in an ##Attributes.ini file to override the Package.ini settings at the directory level.
For example, you can set the isolation mode at the directory or application level to determine which files and registry keys are visible and written by the virtual application you create. The detailed setting in the ##Attributes.ini file overrides the overall Package.ini setting. The Package.ini setting determines the isolation mode only when ThinApp does not have ##Attributes.ini information.
The ##Attributes.ini file appears in most folders for the captured application. For example, the ##Attributes.ini file might be located in C:\Program Files\VMware\VMware ThinApp\Captures\Mozilla Firefox 2.0.0.3\%AppData%\##Attributes.ini.
