Always trying to free up some space on the C drive and keep reading about clearing the cache and deleting it from the C drive?  Here's the solution !

Your phone must be hacked and open4all patch applied and of course a strong file manager to copy/edit files and change attributes.

Let's start then :

1- Delete everything from C:\system\cache except for the vss folder

2- Copy cache folder : C:\system\cache (including the vss folder) to E:\system so you'll get  E:\system\cache

3- Set the attributes of the cache and vss folders in E to "hidden" and "system"

4- Copy Z:\private\10202be9\101f8557.txt to your memory card, and then to your computer.

5- Open 101f8557.txt on your computer and rename every instance of c:\\system\\cache to e:\\system\\cache. (generally : 0x3, 0x4 and 0x8 strings)

6- Put the modified 101f8557.txt to C:\private\10202be9 and change its attribute to "read only"

7- Restart your phone.
