I have have fulfilled all the access requirements, but still cannot download data of ROSMAP. Got an error message as "Could not download any files from the download list." when I was trying to create the download package.

Wow. That simple? Please make it clear in the error message.
Thanks. I've learned that a file download package is limited to 2GB in size. Each of the two files you mention are 5GB, so you will have to download them individually, rather than adding them to a package. Also, if you are downloading large amounts of data you may wish to use the [Synapse Python client](https://python-docs.synapse.org/build/html/index.html) rather than your web browser.
Sorry, yes. "CAN"
> Individual files cannot be downloaded Did you mean "Individual files **can** be downloaded" ?
The file that I can download is part of the package failed to pack. https://www.synapse.org/#!Synapse:syn4212538 https://www.synapse.org/#!Synapse:syn4212540 are two examples. Individual files cannot be downloaded, but not for package.
Thanks for checking. Can you also check what happens if you put the exact same, single file into a download list, and try to download? Does it fail? If so, what is the Synapse ID ("syn123456") of the file that exhibits the problem?
The single file downloads fine. Yes. Seems to be a packaging problem.
Sorry for this inconvenience. To help narrow down the source of the problem can you try to download a single file (for the moment, do not try to create a download package) and say whether it works.
Governance has confirmed that @liucy has the required access, and he has accepted the AD portal additional click-wrap agreement. Can someone from the Synapse team please take a look
