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 send the .ptx alone or the whole folder?

Always the whole folder, zipped. Without the Audio Files subfolder, every region will be offline.

Will third-party plug-in settings survive?

Settings travel with the .ptx as plug-in state data. The recipient needs the same plug-ins installed to load them.

What about session file backups?

Up to you. The .ptx alone is enough; the Session File Backups folder is optional and can save space if removed.

Can the session open in any DAW?

No. .ptx is Pro Tools only. Export AAF for cross-DAW handoff, or render stems.

How to send a Pro Tools session.

A Pro Tools session is not a single file. It is a folder with the .ptx, the Audio Files, the Fade Files, and the backups. quik.space takes the zipped folder byte-for-byte. The recipient unzips, opens the .ptx, and every region is online.

What is a Pro Tools session?

Pro Tools session files use the .ptx, .ptxt extension with no single standard MIME type. The format sits in the audio category. Typical files run 100 MB - 5 GB (session folder), which is well above what most email services will accept as an attachment.

Why you can’t email a Pro Tools session

A Pro Tools session folder contains the .ptx, the Audio Files folder, the Fade Files, and the Session File Backups. The audio alone runs gigabytes. Email cannot carry it.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 Pro Tools session

quik.space takes the zipped session folder byte-for-byte. The recipient unzips, opens the .ptx, and every region maps to the right file because the relative paths inside the zip survive. The share page renders an inline HTML5 audio player, so the recipient streams the file before downloading the original.

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.
