You are correct. The Windows.db
file is used for Search Indexing. 116 GB is quite large and rebuilding it will likely result in a much smaller size. For example, mine is only ~800MB.
Delete and Rebuild
You can have Windows delete and rebuild the search index via "Indexing Options" in the Windows "Control Panel":
- Open
Control Panel
and click on theIndexing Options
icon
or: WIN+R then typecontrol.exe srchadmin.dll
and click OK - Click on the Advanced button
- Click the Rebuild buton
Note: while the Indexing database is being rebuilt, using searches may be very slow or incomplete.
