I've setup and use plugin for several days. Today I noticed a huge amount of strange files in my bucket, they look like:
The size of each vary from 100-200 bytes to 300-400 kB (sometimes 1-2 mB). As I understand the files appear after (or with) every hit to my site with w3 total cache.
Could anyone please explain me what are this files, where they come from and how to avoid them to appear in the bucket?
