If you use Advanced mode when you unpack a Project, you must also specify a root folder, i.e. where to create the Project folder for the unpacked Project. The default save paths for all files are the same as in Simple mode, but in Advanced mode you have the option to change the location (target folder) for each Project file.
You can specify the location for separate files, and you can also specify the location for several files at the same time using
Ctrl + SELECT and
SHIFT + SELECT.
If the Project contains linked Project files, these Project files will by default be stored in a separate folder in the root folder you specify. In Advanced mode you have the option to change the location for these Project files.
