Reflate and Compression Time

[ipman99]

hi, I'm new to fileforums and I don't know if this is the right place to ask. I downloaded Reflate v2 and tried to compress some files with it, and I have 2 questions to ask.

1)I tried to compress 30GB of files at once. but after the process it gave me an empty output. why?

2)In the final step, when it's showing error level=0, why is it take long time to create the .bin file? (Why isn't it showing any kind of a progress like 1 to 100?)
