Or use the GoogleDisk cache instead of the Disk cache? That's what it
was written for. Though apparently you want some kind of odd file naming
format I don't understand; GoogleDisk uses z/x/y.extension.

Ah, perhaps you are using an old TileCache. I recommend upgrading to the
latest, which has solved this problem for you.

The answer to your question is "there is a way, but I wouldn't call it
easy."
