Restore pane shows files in 'Search' pane but not through 'Explorer'

Issue

You can search for files to restore, but they aren’t visible in the File Explorer menu.

Cause

The file index is stored in a local file on your desktop or server. Sometimes, this file is out of date or needs re-indexing. When you search for files, the local index file is ignored, and the backed-up data is scanned instead.

Fix

Delete the local index file. When you try to restore the data, it will be rebuilt with the current index.
The file is located in C:\users\username\temp\ %backup set ID%
