Inside the product
One vault across every storage account
UniDrive routes each upload to the account with the right free space, splits oversized files across drives, and keeps only a tiny index on the server.
Dynamic chunked uploads
Files larger than a single account's free space are split into 500 MB–1 GB parts and dispatched by most-available, round-robin, or priority routing.
500 MB–1 GB parts · Smart routingStreaming and previews
HTTP 206 range requests across chunk boundaries power in-app previews for images, video, audio, PDFs, and text.
Range seeking · Universal viewerSecurity first
Argon2 password hashing, JWT access and refresh tokens, hashed refresh tokens, and encrypted provider tokens at rest.
JWT · Argon2 · EncryptionSharing and API access
Virtual folders, public share links with hashed tokens, per-user invites, and external upload API keys.
Folders · Shares · API keysDisaster recovery
A sealed, per-user encrypted vault manifest is synced to storage so the entire file, chunk, and account topology can be rebuilt after data loss.
Vault manifest · Zero server diskBuild facts
