Downloads stats and number of files

Hi,

I'm looking for a plugin for one of my clients which will handle file downloads. Before we will buy anything we need to be sure that we will choose perfect solution. Two questions:

1. Most important for us are downloads stats. We want to generate report for single file which will show which WordPress users downloaded that specific file (possibly with user contact details).

2. How many files your plugin can handle? We want to use over 1000.

Please let us know about this details.

Best,
Michal
