Hello there

I've noticed that my Analog statistics cache files on my sites are very big -200 MB +. Now can I delete it? is there a way to empty the cache?

please advice.

you may do this wihtout lossing any data or configuration (of course except your cache data) by command:

echo > cache_files
this command will empty this file but save name, permissionj, owner and group. But, as i remember, awstats generate few files which contain cache data and in this case you will need empty each file.
