Hello,

I have one exchange server that isn't like the others.   I have one exchange 2013 server that has in the e:\db (where I store the database files) subfolders called BD62DF7D-0078-44E4-A1A1-23319ACE965612.1.Single, BD62DF7D-0078-44E4-A1A1-23319ACE965612.2.Single, BD62DF7D-0078-44E4-A1A1-23319ACE965612.e.Single

And in those subfolders are other subfolders - indexmeta, journal and MS.    

Indexmeta has a fastsearchindex file - no extension

Journal has master master.@meta, section0, section0@meta, section1, section1.@meta

MS has a %default with a bunch of part...merge subfolders.

They are starting to take up space.

I don't know if I need all of the BD62DF7D-0078-44E4-A1A1-23319ACE965612.2.Single folders?

Can I delete stuff?

Those are the content indexing folders.  I would leave them alone.

Hi,

This folder contains the Exchange content index catalog. Deleting this folder will make additional disk space available when we reseed the search catalog.
