◆ $create_base_container_for_multiple_root_entries

bool ilObjFileAbstractZipProcessor::$create_base_container_for_multiple_root_entries = false

protected

@description Unzip on operating systems may behave differently when unzipping if there are only one or more root nodes in the zip.

Currently, the behavior is the same as in ILIAS 7 and earlier, that in any case the zip structure is checked out directly at the current location in the magazine. If this value is set to true here, another category/folder will be placed around the files and folders of the zip when unpacking if more than one root-node is present. For example, macOS behaves in exactly this way.
