How to share large files securely without an expiry date

Email and chat have size caps. A transfer send solves that: a URL for the ZIP, fast. The extra Spike gives you is a library under the send, so the same files are still there if someone asks again next week.

Sharing at this scale should look like a library with a door. The files sit still. You hand someone a key. You can change the lock without packing the boxes again.

What a send does not include

Email and chat are great at conversation, not at holding a 40 GB set. Transfer tools solved the send: a URL for a ZIP, fast, with almost no setup. Spike keeps that send and adds a library underneath, so the same files are still there if someone asks again next week.

• A library you can open again, not only a one-time pipe.
• A preview that is not automatically the master file.
• Optional password, expiry, or a price on the same URL.
• The folder still yours after someone downloads.

What "secure" should mean

Secure is not a marketing word for HTTPS. For a working file share it means: nothing is reachable until you publish a link; you can require a password; you can expire or revoke that link; and the preview is not automatically the master.

Spike keeps folders private by default. Sharing is a switch. You can leave a link open, hide it from casual traffic, lock it, or attach a price so the download is the purchase.

A secure share is a door on a library, not a parcel you toss over the fence.

Preview without giving the original away

Clients and collaborators need to see what you sent. They do not always need the print file, the uncompressed master, or the layered PSD on first look. Protected previews exist for that gap. Blur a gallery. Watermark a still. Let someone scrub a video without a clean export sitting in their downloads folder.

That is also how sharing turns into selling without changing tools. The same page can stay a review until you put a price on it. Read the longer note on blur and watermarks if stills are the product.

Passwords, privacy, and who can open the link

Not every delivery should be guessable. A password is the difference between "anyone with the URL" and "the person you briefed." Privacy settings on the folder decide whether the page is a quiet hand-off or something you are willing to put on a storefront.

When sharing should become selling

If you are about to send a finished gallery, a pack of stems, or a course PDF, and you still have an unpaid invoice, do not split the job. Put the price on the folder. The paid download link is the share plus checkout. The recipient already has the page. Payment is the unlock, not a new conversation.
