1. Are you online?
The dashboard shows a small "offline" indicator in the sidebar when your connection drops. Reconnect to Wi-Fi and uploads resume automatically.
2. Is sync paused?
On iOS, check Settings → Sync. On web, the orange banner at the top of the dashboard shows if sync is paused. Unpause to resume.
3. Is your workspace full?
If you're at 100% storage, uploads fail silently. Dashboard → your avatar → check storage usage. Upgrade, delete files, or empty Trash to free space.
4. Is the file unusually large?
Each file can be up to 500 MB on Free and up to 5 GB on Pro and Ultra, on every platform. Anything bigger needs to be split first — for example, into a multi-part ZIP archive.
5. Force a resync
iOS: Settings → Sync → Sync now. Web: refresh the page (Cmd-R / Ctrl-R) to re-trigger the upload queue.
If none of these work, email
support@virtualdrive.us with the file name and approximate size. We can pull server-side logs to find what's blocking it.
