/cache is empty

Hi,

I have a stock LT4 with Philz Kernel and so far everything runs fine.

The only thing which is strange is my empty cache partition.

When I navigate to /cache with Root Explorer I have 200 MB free and only one file in it 'hidden_volume.txt'.

The permissions of /cache are rwxrwx---.

Shouldn't here not many of files? What may be the problem here?

Thank you in advance.
Oli
