There is a file size limit of 10 MB on free hosting. Downloads larger than that will get cut off. It looks like your file is almost exactly 10 MB, but due to calculation skew, it might just go over the file size limit.
You could offload those files to a separate file sharing service to distribute the files from, or maybe split the 10 MB file into smaller files to get around the size limit.
I guessed it.
I cannot manipulate that file because it is the result of build from Unity3D.
Not a big issue since i plan to publish on an external service.
Thanks for reply.
