I have installed exchange 2007sp1 into c:\program files\ Microsoft\exchange server but located the mail store on e:\exchange\Mailbox store.
I transferred my old mailboxes to to the new server but eventually they failed as my c:\ disk ran out of space.
I have discovered that under
C:\Program Files\Microsoft\Exchange Server\Mailbox\First Storage group
there are approx 34000 text files appeared called e0000000a or aa or ab etc.
Now I either need to relocate these or get rid of them but I have no idea what they are or what there purpose is or how to deal with them but i can't do much until i get some disk space back.
Any pointers would be most gratefully received.
