The Windows.edb is a database file of the indexing service. If you have enabled Windows Indexing, this file can become quite large. Is it safe to delete this file? More after the break.

Is it safe to delete the Windows.edb file?

When you try to delete Windows.edb without disabling the Windows Search service first, you’ll get an error.

Yes, it is perfectly safe to delete it, however your Windows search will take a longer time to complete because then your index files will be gone. Alternatives like Locate32 can help you in this regard as they are more liteweight and do not occupy as much space as the .edb file can.

You first need to disable the Windows Indexing service and then you can delete the .edb file.

1. Step First of all, learn how to disable Windows Indexing

2. Step Next, make sure you can see hidden folders

3. Step Open the Windows Explorer and go to C:\ProgramData\Microsoft\Search\Data\Applications\Windows which is the default location of the Windows.edb file (it is a hidden folder)

4. Step Delete the Windows.edb file

Alternatives: Use SearchEverything or Locate32

Tip: The Windows Search Indexing can cause a lot of high disk activity. You can disable the service if you like and use programs like SearchEverything or Locate32 instead. However, please keep in mind that the built-in search will take a long time to process any searches if you delete or disable
As mentioned in the intro, if you use the Windows Search feature a lot, you might not want to delete the Windows.edb file or your searches might become slower. On a sidenote, you can also use tools like Search Everything that might be faster than the built-in Window Search or replace the Windows 7 search with FileSeek. This is up to you and you need to decide this for yourself.
