[cobalt-users] Can I clear/reset web.cache web.cache web.stats at /usr/admserv/html/.cobalt/report/ ?

[vadtp1@xxxxxxxxx]

Many days now I have yellow light on Disk Usage
But no yellow light is on "Operating System and Programs" & "Virtual Sites"
All the sites light is green,  so no user exceed his space

So I do "df" command and this the result
Filesystem           1k-blocks      Used Available Use% Mounted on
/dev/hda1               743466    669570     73896  90% /
/dev/hda3               198601     17782    180819   9% /var
/dev/hda4             17671528    545914  17125614   3% /home

I do a "find / -size +5000k "
and I found big files at  /usr/admserv/html/.cobalt/report/
46372221 web.cache.new
45996228 web.cache
 7786968 web.stats
 1067363 ftp.cache.new
 1066278 ftp.cache
  996385 ftp.stats
  156474 mail.cache.new
  155758 mail.cache
  105658 mail.stats
   13537 stats.tab
    1108 main.web.dat
    1059 www.DOMAIN-NAME1.web.dat
    1059 www.DOMAIN-NAME2.web.dat
    1059 www.DOMAIN-NAME3.web.dat
    1059 www.DOMAIN-NAME-N.web.dat

Can I delete all this files?
or reset a file to zero ?
like this "echo > web.cache"
I don't care if I clear the stats but I don't want to have any other problem
to my raq

also I have many "www.DOMAIN-NAME-N.web.dat" files from old domains were was
in the raq at the past
can i deleted this files ?

Please help me... give me your advices

Thank you (sorry about my English)
