<div style="font-size:10.0pt;font-family:Verdana,Arial"> Hi,<br>
<br>
I'm not sure this is due to some configuration option, bug or
feature, but I'm observing some folders on Cyrus HTTP WebDAV
server having hundreds (995 at this moment to be precise)
internal files in the format "NNN." that correspond to the
same file but different versions in time.<br>
<br>
There are 2-3 files (xls) in the folder that are edited
constantly during the day and it looks like each save
operation creates a new file. The files are of some 3-5Mb
each. In the explorer/web view there are only a couple of
files with a total size of 17.5Mb, but the reported disk usage
for the folder is of 1.6Gb.<br>
<br>
Could someone please shed some light on what's going on and
how to make each file visible to the users to be stored in
only one internal file?<br>
<br>
Thanks,<br>
Anatoli</div>

<p>Because *DAV is layered on top of an IMAP store, we have to abide
by IMAP semantics in which messages (in this case DAV resources)
are immutable. Therefore, we can NOT overwrite an existing
message in the mailbox. Each change MUST result in a new
message. However, the server does mark the previous version(s) as
deleted and expunged, which means that they will eventually be
removed by cyr_expire. If you aren't running cyr_expire, you
should consider adding an event to cyrus.conf to remove expunged
messages (see -X option).<br>
