SyncFileBox is a controlled file exchange for design & construction teams — collect drawings and models from contractors, keep revisions and supersessions under control, and share back with a complete audit trail.
Every exchange is a dated transmittal — a tracked package of files, never a loose email attachment.
Contractors upload a transmittal through their own tokenized portal link. No accounts, no passwords to manage — optional passcode if you want one.
Your desktop pulls new transmittals through the REST API with presigned downloads — every file's SHA-256 verified on arrival.
New revision supersedes the old, duplicates are caught by hash, overwrites are flagged — and the outcome is written back to the audit trail.
Send files back as a tracked transmittal. Contractors download from their own portal page — same link, same audit trail.
Small enough to set up in an afternoon. Strict enough to answer "who sent what, when?" a year later.
Each contractor gets a private upload & download link per project. External parties click a link — they never have to create an account.
ISO 19650 file names parsed automatically — revision, discipline, status. Custom regex or manual entry when contractors do their own thing.
Every file gets a SHA-256 on upload. Duplicates are detected deterministically, and every download can be verified against the original.
Who uploaded, who downloaded, what superseded what — every event recorded with timestamp and hash. Nothing is silently overwritten.
Large models upload straight from the browser to object storage over presigned URLs — no size-limited middleman in the byte path.
Clean JSON API with bearer-key auth: list transmittals, presigned up/downloads, audit write-back. Built for desktop and pipeline integration.
SyncFileBox handles the exchange. FileMuster, its desktop companion, reconciles everything against your project folders.
Give every contractor a link, keep every revision accounted for, and let the audit trail answer the hard questions.
