ZAR (Paid version) & Media Card

Well once again, I had my 5345935th problem with a media card, and had to backup. I used a paid version of ZAR, and I think it has backed up all my files. The files have been spread around into different folders, so I will have to reorganise them myself. Although, I have noticed some random files in a format that I don't know, such as "$__ file format", "H__ File", and a bunch of other symbols. I've also noticed that in the podcasts folder, they are also in these random formats, but roughly 20 files together added up to being 44GB big? My media card is only 16GB and was about 80% full... Anyone have an ideas on what these could be?
