Original-file hosting. No built-in video player for this container.
The WMV sample opens in Flat's file download view. Flat does not provide a Windows Media decoder.
ASF is the container commonly used for WMV video. It can carry different stream types and codecs. The recipient's application must support the contents of the file.
Public links open without a Flat account. Several files open in the explorer, where readers can choose a file. Original downloads remain available.
The exact path /motion.wmv serves the original file. Opening that URL does not convert its container or codecs.
How to upload WMV and ASF files and get a link
Prepare your files
Open the source file in a compatible desktop player and check its audio and video streams. Keep the original filename and any playback requirements with your handoff.
For browser viewing, export a separate modern delivery copy with your own tool. Protected Windows Media files remain protected; hosting does not remove encryption or license requirements.
Publish from your browser or terminal
In your browserGo to uploaderDrop, publish, copy the link.
Select your finished files in the uploader above. Enter your email if signed out, then choose "Publish videos".
Selected files need unique names and publish at the top level. The browser uploader does not accept folders or extract ZIPs. Use the CLI when relative paths matter.
TerminalNode.js 20+One command. Files or folders.
npx -y @getflat/cli deploy ./motion.wmvReplace the example path with your file, or pass a folder path to preserve its structure. The CLI prints the published URL.
Check the published result
Download the file and open it in the receiving application. Check picture and sound before sharing the link more widely.
Signed-out uploads expire after 1 hour by default. Sign in before expiry to keep them online, or sign in before publishing for no default expiry.
When to use WMV and ASF hosting
Older presentation videos
Deliver an existing WMV used by a presentation or desktop workflow without changing its source format.
Windows Media transfers
Send an ASF or WMV original to a recipient who has the tools to inspect, play, or convert it.
Keep a version, or keep an address.
Share this version
Every upload gets its own link. Publishing revised files creates a new link and leaves the earlier version unchanged. Use the version link when someone needs to review a specific upload.
Update files at one address
Use a named onflat.page address or your own domain. Sign in, then publish with the CLI using --domain. Publish revised files with the same domain to point that address to the new upload.
Named addresses are included on Free. Adding your own domain requires a paid plan. The browser uploader does not set up or repoint these addresses.
WMV and ASF hosting questions
Is hosting free, and what are the limits?
Yes. Signed-in Free includes 5 MiB per upload, 1 GiB of storage, and 5 GiB of monthly transfer, with no default expiry. The per-upload limit covers all files in that upload. Paid plans raise these limits.
Do readers need a Flat account?
No. Public links open without a Flat account. Anyone with the link can open the uploaded files. Password-protected links also require the visitor password.
Can I password-protect my upload?
Yes. Password protection is available on every plan. Add --password YOUR_PASSWORD to your CLI deploy command. It protects access to the upload and its files, but does not prevent someone with access from saving a copy. The browser uploader creates public uploads.
Can I replace files without changing the link?
A version link always refers to its original upload. For same-address updates, use a named address or your own domain. Publish revised files with the same --domain value in the CLI to point that address to the new upload.
What happens when an upload expires?
Flat stops serving it. An expired upload cannot be recovered. Signed-out uploads expire after 1 hour by default. For browser uploads, use the sign-in link shown after publishing. For CLI uploads, run npx -y @getflat/cli login. Complete sign-in before expiry to keep the upload online. If you chose a shorter expiry in the CLI, that deadline stays in place.
Is WMV a container or a codec?
WMV names a codec family and is also a common filename extension for video in ASF. Check the actual stream information rather than inferring it from the filename.
Will Flat remove Windows Media protection?
No. Flat preserves the uploaded bytes and does not decrypt protected media.
How large can a video upload be?
Upload allowances depend on your plan and cover all files in the upload. Compare current plan limits. A larger upload allowance does not add codecs, container support, or transcoding. Original files remain downloadable when a preview is unavailable.
Can I embed this file on my website?
You can link to the original download. An HTML video element does not add a decoder for this container. Export a browser-compatible viewing copy with your own tool if you need embedded playback. Flat does not convert the original.
