I tried File's SMB support but found that larger (100+ MB) transfers fail for no apparent reason (1). Third-party apps' SMB support is much better - I had success with Readdle's Documents, Goodreader, and most recently FileBrowserGO. My slow-to-moderate internet speed may play a role; however even connecting to my laptops SMB share over a wired connection was fraught with issues. 1: the failed but in-progress transfers often stick around with no way to remove them. They're gone after restarting the device, though.
