>>Is there an easy way to move folders and all its contained files from a subgroup to the main group, or between subgroups?
No. But if the files are currently in the main group, you may be able to provide access to them in a subgroup via a hyperlink (perhaps in a wiki page).
>>Alternatively, how does one download an entire folder without having to download each individual file?
Your best option may be to use the group export function found at Admin>Settings. Click on the Export Group Data button at the top. Select only the Files area and click on Export Group Data again. Wait 10 minutes and you will get all the files through a link in your email. At that point you can open the ZIP archive, navigate to the desired folders and extract them.
Note that file ownership information, file descriptions, etc will not be retained.
Hope this helps,
Bruce
