sorting of data files

Hello,

i'm new to Document Cloud.

I'm mostly using Acrobat Reader in combination with the Document Cloud for university studies.

I wanted to collect all my lectures in several folders.

Those folders should be named: 1. semester, 2. semester,... and so on!

When I reach the number of "10", the folder with the name "10. semester" is not sorted correctly after the folder "9.semester"!

Instead it is sorted after folder nr. 1 ?!

By the way, this sorting problem only exists on my mac, my iPad/iphone shows the correct sorting!

Can somebody help me?

Thank you in advance

Christoph
