Hello Support team,
We tested DriveHQ FileManager App for iPad (and iPhone), it can upload files larger than 100MB without any issues. We realized the problem was with the browser based upload method, e.g. the DriveHQ's True Drop Box folder feature. Indeed there was a problem with the browser-based upload on iPad/iPhone affecting large files. The problem has been resolved. Please let us know if you still experience any issues.
