I have a relatively big git repository on Team Foundation Server - almost 3GB due to  - but after a certain amount of time server resets the connection around 1GB - too slow download speed with 120-100 kbit/s
I was trying to clone it using downloading via zip and then add remote and do pull. But it considers all the files as new. 
How to clone such repository?
P.s. I know that it should not be that big and the files there should not be stored in git repo at all, but I don't have the option to move them.
