If a file or folder is shared completely within the folder that is exported, all the shares links will be imported and shared as before.

However, if there are links in a share that are outside the root of the export, those links are not included in the share, and if all share links are out the export folder, then the file or folder is not shared at all in the imported folder.

For example, if $/example1 is exported, and $/example1/foo.txt is shared to one other place at $/example2/foo.txt, then the imported file foo.txt will not be shared after the import, because none of its share links exist within the imported folder.
