I noticed you added this feature. The timing of the file viewer on older
phones has been affected making bitpim slower.
The vx6100 timing on the root expansion has gone from 1200ms to 3100ms.
On the vx4400 it has gone from 800ms to about 1700ms.
Expanding other directories is slower depending on their content. The extra
delay is incurred every time the directory is expanded. There is a more
traffic over the serial port when manipulating the file system.
A once off complete filesystem read would be a more efficient way to achieve
the same result, the initial delay would be higher but subsequent use would
not be slowed down.

When an expanded tree view is collapsed and re-expanded (or refreshed) it
visibly collapses all of it's subdirectories even if they were previously
expanded, the previous behavior of the old filesystem view was to leave
subdirectories in the same state they were previously.
