Yes. Up to 100 MB per file and up to 3 files per request are free. Files expire in 72 hours unless you pay $2 to extend by 30 days, or pay to group them into a 30-day space for $5.

Do I need to sign up?

No. Anonymous use is the default. You can optionally attach your email so you can recover files later if you lose the share link.

How long do files last?

Free files expire in 72 hours. After that there is a 7-day grace period during which a $2 extend will bring the file back for 30 more days. After the grace period the storage is permanently purged.

Can AI agents use quik.space?

Yes. quik.space exposes an MCP (Model Context Protocol) server and accepts the x402 standard for stablecoin micropayments on Base. Agents do not need API keys or signup — their wallet is their identity.

What file types are supported?

Any file up to 5 GB. The recipient page renders inline previews for images, audio, video, PDFs, markdown, HTML (sandboxed), Microsoft Office docs, and plain text or code.

Should I use Save Project for Melange?

Yes. It collects every texture, proxy, and dependency into one folder. Zip and upload.

Will Redshift or Octane settings travel?

Yes, scene state is preserved. The recipient needs the same renderer installed.

What about cached simulations?

Cache files live in a sibling folder. Include them in the Save Project export.

Can the recipient open C4D scenes on Mac and Windows?

Yes. Cinema 4D scenes are cross-platform within recent versions.

How to send a C4D file.

Cinema 4D scenes are dense, simulations, caches, textures, references. The bundled project folder is the only safe thing to ship. quik.space takes the zipped project byte-for-byte and gives the recipient a clean download.

What is a Cinema 4D file?

Cinema 4D file files use the .c4d extension with no single standard MIME type. The format sits in the 3d category. Typical files run 20 MB - 2 GB, which is well above what most email services will accept as an attachment.

Why you can’t email a Cinema 4D file

A Cinema 4D scene with simulations, baked caches, textures, and high-poly geometry routinely hits 500 MB to 2 GB. Email caps make this impossible.Slack, Discord, and most other workplace tools have similar caps, often around 1 GB for free tiers and with aggressive per-channel storage limits. Even when the file fits, it counts against the recipient’s mailbox quota forever.

How quik.space handles Cinema 4D file

quik.space stores the .c4d byte-for-byte. Use File > Save Project for Melange to bundle every asset; zip the result and upload. The recipient opens it in C4D with everything in place. The share page does not render 3D scenes inline. The recipient downloads the file and opens it in the matching DCC.

The file lives for 72 hours by default and then enters a 7-day grace period. We do not train AI on your files. We do not share them with third parties. After grace, the bytes are permanently purged from storage. Read the full policy on privacy.
