Version 0.9.2.3 In preparing for a migration to a new server, we found that W3TC was creating thousands of redundant directories, mostly for the folders "static" and "buyers" which are for the 2 self-hosted CDNs. This is a sampling:
./public_html/wp-content/uploads/home/*****/public_html/wp-content
./public_html/wp-content/plugins/w3-total-cache/wp-content
./public_html/buyers/wp-content ./public_html/buyers/wp-content/wp-content
./public_html/buyers/buyers/wp-content
./public_html/buyers/buyers/buyers/wp-content
./public_html/buyers/buyers/buyers/buyers/wp-content
./public_html/buyers/buyers/buyers/buyers/buyers/wp-content
./public_html/buyers/buyers/buyers/buyers/buyers/buyers/wp-content
./public_html/buyers/buyers/buyers/buyers/buyers/buyers/buyers/wp-content
./public_html/buyers/buyers/buyers/buyers/buyers/buyers/buyers/buyers/wp-content
./public_html/buyers/buyers/buyers/buyers/buyers/buyers/buyer/buyers/buyers/wp-content
./public_html/buyers/buyers/buyers/buyers/buyers/buyers/buyers/buyers/buyers/buyers/wp-content
./public_html/buyers/buyers/buyers/buyers/buyers/buyers/buyers/buyers/buyers/buyers/buyers/wp-content
./public_html/buyers/buyers/buyers/buyers/buyers/buyers/buyers/buyers/buyers/buyers/static/wp-content
./public_html/buyers/buyers/buyers/buyers/buyers/buyers/buyers/buyers/buyers/buyers/static/buyers/wp-content
./public_html/buyers/buyers/buyers/buyers/buyers/buyers/buyers/buyers/buyers/buyers/static/static/wp-content
./public_html/buyers/buyers/buyers/buyers/buyers/buyers/buyers/buyers/buyers/static/wp-content
./public_html/buyers/buyers/buyers/buyers/buyers/buyers/buyers/buyers/buyers/static/buyers/wp-content
You get the idea. Tried deleting the redundant files, but they would be recreated in minutes. Had to disable W3TC
