Create a folder within the share.
Move the savepoint files within the share and resume the restore from manifest.
For Example:
\\10.6.7.156\D$\level1\DBSIvlanTester_20130401_090355_F.Manifest.metadata
\\10.6.7.156\restoreSP\level1\DBSIvlanTester_20130401_090355_F.Manifest.metadata
Note: This does not affect savepoint files that are in their original location or standard restores from the savepoint grid.
