Limit the number of files created

Any solutions here? I have a similar issue. I already hit the file quota and no longer able to upload any files. I am using W3 Total Cache, too.

I cleared cache, and my webspace freed up quite a bit.

I have same problem. I use this plugin over 2 year. After update my wordpress admin panel start worked very slow. Cache did not clear from admin panel.
Then I saw quantity files created in cache directory it’s over 400Mb
When I deactivate plugin (rename W3 Total Cache plugin directory and delete setting files in wp-content + delete cache setting in wp-config.php) always work well.

I use godaddy hosting deluxe plan
My site has over 1100 posts + 1000 tags, WordPress vers 3.5
Until this problem I have this strange bandwidth statistic.

Files from cache directory is deleted file manager over 12 hours( now not yet deleted )

I had same issue. Given the lack of response from the creator I can only assume it is what it is with no solution. I know the plugins are free, but no support equals crap plugin.
