Hi Ivan,

Firstly I'm sorry that I haven't clearly explain my situation.
I would like to know if that 2K-4K limit is applied to only a single layer 
of directories.

For example, the path is /coda/layer1/layer2/layer3. Is it the limit on the 
number of entires in layer1 is 2k - 4k, including those under layer2 and 
layer3? Or those under layer2 and layer3 are excluded?

Best regards,
