Windows 11 Search Slow? Speed Up Search in File Explorer

Published by Nyau Wai Hoe - Updated on

If you often search your PC using the search bar on the Start menu or File Explorer in Windows 11, you may sometimes feel that the search is unusually slow, taking too long to produce any result (constantly showing “Working on it…”).

It is especially the case if you are searching for a newly created file, or file from a newly installed software. There can also be times when you are certain the file you are looking for does exist on your computer, but the Start menu or File Explorer search just couldn’t find it.

The major reason that is causing slow search or file not found issue when using the Start menu search or File Explorer in Windows 11 is that the files or folders you were searching for may not be indexed yet. Search Indexing is a Windows feature designed to make finding things on your computer much faster by creating an index of your files. It’s like the index in the back (or the front) of a big book. It lets you find the contents much easier.

By including the files and folders in the index, it makes searching for these files much faster because Windows doesn’t have to search through all your files every time. Conversely, searches will be significantly slow when querying items is not in the indexed locations.

This guide will show you how to speed up search in Start menu or File Explorer by enabling Enhanced search mode and including any file, folder or directory you want to the index in Windows 11.

What is the difference between Classic and Enhanced search in Windows 11

The Classic option is selected by default in Windows 11. When Classic is selected, Windows will only index your user profile’s folders such as Documents, Pictures, Music folders, desktop, etc. It will not index other files and folders elsewhere on your computer. Thus, whenever you search for a file that is not in the indexed locations, the search will take an extensively long time to complete because Windows has to search through all the files for it.

The Enhanced option, however, will allow Windows to index the entire PC which includes every file and folder on all your connected hard disks, except for folders in the “exclude folders from enhanced search” list.

However, Enhanced search mode doesn’t index contents of a file. It will only index basic properties of an item. What this means is that when you search for a file by its name, Windows will be able to find it extremely fast because the name is a property of the file that has already been indexed. But if you search for the file using words within the contents of the files, you may not find the file or the search may take extremely long to produce any result.

To solve this, you can manually add the directory or folder to the “Indexing Options” to have all of its contents indexed.

Note that the process to index folders this way is very resource intensive and may take days to complete if you include hundreds of gigabytes of files to be indexed. However, the indexing will only run when Windows detects that your computer is in idle mode – when you are not doing anything at all.

After the indexing of the locations is completed, you will be able to search for those files by its name, other property or even contents within in on the Start menu search bar or File Explorer, and Windows should be able to find them extremely fast.

Exclude folders from enhanced search

If you select Enhanced search mode, you can exclude any folder from being indexed by adding the folder you want to exclude to the “Exclude folders from enhanced search” list in Settings > Privacy & security > Searching Windows.
