Contracts, quotations, design drawings and financial vouchers are scattered across personal drives and chat groups — impossible to find at critical moments, impossible to take back once sent. SBK Cloud Disk provides enterprise-grade file storage, a Windows / Mac desktop sync client, five-level permissions, version management, secure share links, full-text search and encryption & data-leak prevention — files truly 'live in the cloud, under your control'.
Storage, sync, permissions, versioning, sharing, search, encryption & DLP — full lifecycle management of enterprise file assets
Personal / team / department / company folder tiers — storage partitions that mirror your org structure with clear ownership
Five permission levels — view / download / edit / delete / manage — configurable by user / department / role
Every save creates a new version; roll back to any prior version anytime, and lock key versions against overwrite
Full-text indexing of Word / PDF / Excel content — locate any file by keyword in milliseconds
Who uploaded / downloaded / shared which file and when — everything is logged for compliance traceability
Right in the Explorer sidebar — incremental sync / conflict-safe duplicate copies / offline access / on-demand placeholders
Preview Office / PDF / images / videos without downloading; on mobile, see the picture without taking the file
Three-classification transparent encryption, outbound approval / screen watermarks / download control — sensitive files never cross the company boundary
Deletions land in the recycle bin first — one-click restore during retention, so accidental deletion is no disaster
Allocate storage quotas by person / team / department, with usage alerts to keep costs under control
Real-time sync across Web / Windows / Mac / iOS / Android — edit once, up to date everywhere
Four capabilities for the four most painful enterprise file scenarios
v7 → v8 paragraph-level diff
A contract goes through 10 revisions and nobody knows which is final; a design is finished only to learn the client wants the version from three rounds ago. SBK Cloud Disk maintains version history automatically — every save is a version with editor and timestamp, and rollback takes one click.
Link access log
The usual way to send a proposal to a client is a chat or email attachment — out of your control the moment it leaves. SBK Cloud Disk share links support passwords, expiry, download limits and IP restrictions; they auto-expire and can be revoked even after being sent.

After installation, a "☁ SBK Cloud Disk" node appears in the Explorer sidebar, OneDrive-style: files show as placeholders, download on double-click, and save back to the cloud automatically on edit. Offline you keep working with local copies; once reconnected, incremental sync catches everything up.
Security audit log
Quotations, contracts, 3D originals and core process files are classified normal / confidential / top-secret: servers and local disks store only ciphertext, decrypted transiently on open; confidential files need approval to download or send out; top-secret files can only be viewed and edited inside the sandbox — watermarks and audit logs cover everything.
The latest quotation templates, product brochures and case decks live in the team disk — reachable from a phone on the road, always the newest version.
Design sources, 3D drawings and code backups in the team disk with rollback; top-secret originals are sandbox-view-only, and departing employees can't take assets with them.
Scanned contracts, invoices and audit materials archived by year; external auditors get controlled links instead of emailed originals — links expire automatically.
Replaces Dropbox / Google Drive, which are unreliable inside China — locally hosted servers keep sync fast between domestic and overseas branches.
Send drawings and proposals to factories and clients via controlled links: password + expiry + count + watermark + revocable — what goes out can still be called back.
Headquarters policies and training materials are published read-only in the company public space — every branch always sees the same, latest version.
Files are the carrier; business is the process — the disk connects natively with the SBK suite
OA attachments settle into the cloud disk; approvals, reports and announcements reference disk files directly
Structured online documents complement disk files; business documents bind to disk entities for unified control
Approval attachments come straight from the disk, and outbound requests run through approval flows — no re-uploading
Tasks link to disk files so collaboration never loses context, and deliverables archive automatically
Send disk file cards in chat — preview online without landing on devices, forwarding constrained by permissions

Baidu Netdisk targets personal entertainment storage, and Dropbox / Google Drive is unreliable to access inside China; SBK Cloud Disk is an enterprise file-asset platform: folder tiers mapped to the org structure (personal / team / department / company), five-level permissions, operation auditing, three-classification encryption & DLP, deep integration with OA approvals, documents, tasks and instant messaging, plus locally hosted servers in China for guaranteed speed and compliance.
The client uploads in 4MB chunks with resumable transfer — a multi-GB file interrupted mid-way only re-sends the missing parts; identical files are de-duplicated via SHA-256 fingerprints for instant upload; desktop sync transfers only incremental changes with controllable bandwidth, and you can cap upload / download speed in the settings panel.
File assets live in the company cloud disk, not on personal computers: once a departing account is deactivated, files in their personal space can be handed over to a successor in one click, while team / department / company spaces belong to the organization and are unaffected; deleted content can be restored from the recycle bin during the retention period, and all outbound share links can be revoked — no more 'files walk away with the person'.
Yes. File metadata lives in MySQL, and file blocks can be stored on local disks or self-hosted MinIO / OSS with zero public-cloud dependency; the sync client and preview services (including only-office) can all run inside the enterprise intranet, meeting the localization and compliance requirements of manufacturers and trading companies for sensitive drawings and contracts.
