  • Question

  • Hi, i have a larger number of .merge files on both of my exchange 2013 servers.  these files take up a log of space.  I have read that they are search index files. Can any one tell me what these files are and can some or all of them be deleted safely.  Thank you!

  • Hi pctek,

    Welcome to our forum.

    For deleting those files, we suggest you move them to another place, then we could delete it if there are no any issues after we move them to another place.

    Best Regard,

  • Thanks, a little Leary about moving them as I don't want to bring the system down.  If they are needed, will it be easy to just put them back and get everything backup and running?

  • So still not sure if I can delete some of the files to free up space.  I understand that they are search index files, but do I need to keep them all?  Is there some way to remove the oldest ones?  Thanks in advance for any help.

  • You should share the file paths and some of the filenames so that we're clear on which files you're asking about.

    By the way, you've posted in the wrong forum.  I suggest you move the thread to the Exchange 2013 forum.  I'd do it for you but they haven't made me a moderator in the legacy forums.

    Also, what cumulative update level are you at?
