Why the extracted files are much smaller than the *.sens file? #147

Hi, I downloaded the dataset and used the https://github.com/ScanNet/ScanNet/blob/3e5726500896748521a6ceb81271b0f5b2c0e7d2/SensReader/python/reader.py to extract files from the .sens files. The original .sens file is around 3.7 G, but the extracted files only add up to 2.3 GB. I'm wondering if this is normal, or if I'm missing something here. When I check the script, it seems no frames are skipped(skip=1). Why there is such a huge difference in file sizes? Is this something I should be worried about, or is it all good?
