 I think there is an issue with IIS and compression.

 I have two MP3s, one is around 7MB and the other around 2MB. I can
 "download to folder" for both and that works fine, but if I play in the
 browser the 7MB version cut off after 30seconds (I tried this on multiple
 MP3s larger than 5MB). I thought this had something to do with the
 "Transfer-Encoding      chunked" header. Upon further investigation I
 found that to disable this, I just had to specify the Content-length,
 which is explicitly disabled for IIS in ms-files.php (line 42). I
 commented out that line and now everything is working fine. I'm sure there
 was a reason for it, but I am not sure what for.
