What is Max File Size & No. of Files for Free Airdroid Version?question

I have recently upgraded to Premium version mainly to get rid of adverts, which entails a regular monthly payment. However, on reading the Premium version benefits, it talks about larger file sizes and unlimited number of files. To enable me to make an informed decision on whether to retain the Premium account or revert to the free version, I do not know what the max file size would be or max number of files (photos), etc and cannot find this info in the standard Airdroid details.
