A problem when using connect drive

Hi:

I use connect stick 32G and iphone, and when using the connect drive to open file using good reader, I found the connect 

drive app will buffer the data, and not release it. After checking my download, it’s empty, but it still keep the data 

in buffer(I see it in setting). Is that possible to delete the buffer of the connect drive, like the function of it’s playing app.

Thanks.

as far as I can tell there is no option in the settings to clear the cache. if you uninstall and reinstall the app it should also delete the cache.
