Is It Safe to Delete .Spotlight-V100?

What is .Spotlight-V100?

.Spotlight-V100 is a hidden system folder created by macOS at the root level of every hard drive, external drive, or USB flash drive you connect to your Mac.

Why Does It Exist?

It contains the search index database for Apple’s Spotlight Search feature (Cmd + Space). By indexing all the files, documents, and metadata on the drive, Spotlight can instantly find the files you are looking for instead of having to manually scan the drive every time you search.

Can You Delete It?

Yes, with caution.

Deleting .Spotlight-V100 is not dangerous to your personal files, but it will instantly break Spotlight search for that specific drive until macOS rebuilds the index. You should only delete this folder if Spotlight search is returning incorrect results, failing to find files, or if the index file has become corrupted and bloated.

How to Delete It

Because it is a hidden, root-level system folder, the easiest way to delete it is via the Terminal:

1. Open Terminal.
2. Type sudo rm -rf /.Spotlight-V100 (for your main drive) or sudo rm -rf /Volumes/[DriveName]/.Spotlight-V100 for an external drive.
3. Press Enter and type your administrator password.

Alternatively, you can force macOS to rebuild the index without using the Terminal by going to System Settings > Siri & Spotlight > Spotlight Privacy, adding your drive to the list, and then removing it.

What Happens If You Delete It?

macOS will immediately realize the index is missing and begin silently rebuilding a fresh .Spotlight-V100 folder in the background. While the index is rebuilding, searching for files on your Mac will be very slow or return incomplete results. The rebuild process can take anywhere from a few minutes to a few hours depending on the size of the drive.

Bottom Line

You can safely delete .Spotlight-V100 to fix a broken search index, but macOS will simply recreate it automatically, so it is not a permanent way to save storage space.
