Upload a file, copy its **File URL**, and reference that URL from your app. Update the file later and your app picks up the new content on its next fetch — **no rebuild, no redeploy, no re-upload of a 20 GB build for a 2 MB change**. Files are stored on the same infrastructure as the GPU servers that run your app, so runtime reads are sub-millisecond — fast enough to treat like local storage. Find it in the dashboard sidebar under **Runtime Asset Storage** (currently in beta). It's account-level: files are shared across all your projects, not tied to one. ## What teams use it for Seasonal artwork, product imagery, pricing data — change the file, and every new session sees the new content. Move heavy videos and texture packs out of the `.zip`. Smaller builds upload, process, and distribute faster. Serve the JSON or config your app reads at startup from one place, instead of re-packaging for every tweak. File URLs only resolve from apps running on Streampixel's servers — your files are never publicly reachable. This is **not** where Unreal Engine builds go — upload those on your project's Builds page (they don't count against your storage quota here). It's also unrelated to the REST [Upload File API](/resources/api-reference/upload-file-api), which registers builds. ## How it works Choose the region where your project streams (**US**, **EU**, or **APAC**), then drop files onto the page or click **Upload**. Files up to 50 GB each. Every file gets a stable, region-scoped URL — use the copy button next to it. Load the File URL from your Unreal application at runtime, the same way you'd load any HTTPS URL. File URLs look like: ``` https://eu.storage.streampixel.io///MyTexture.png ``` ## Private by design File URLs are served from Streampixel's private network and only resolve from applications **running on Streampixel's servers**. Pasting a File URL into your browser, or fetching it from your own infrastructure, won't work — and neither will anyone else's attempt to. Your files are not publicly reachable. This also means File URLs won't load while you develop locally in the Unreal Editor — point your app at local copies of the files during development, and at the File URLs in deployed builds. ## Regions and sync Files live in the region you upload them to, co-located with that region's GPU servers. If you stream in more than one region, upload the file to each region you need it in (your quota is shared across regions, so you only pay for the space once per copy). After an upload, the file replicates to the streaming servers in that region. The **Sync** column shows where it stands: | Badge | Meaning | | ------- | ----------------------------------------------------------------------------------------------------------------- | | Syncing | Replicating to the region's servers — usually brief. | | Synced | Available at its File URL. | | Failed | Replication hit a problem — retry the upload, or contact [support](mailto:support@streampixel.io) if it persists. | Wait for **Synced** before relying on a file at runtime. ## Storage and pricing Every subscription includes **1 GB** of runtime asset storage. Need more? Add **10 GB storage packs at €20/month each** from the **Buy more storage** button — packs are shared across all regions, and you can add or remove them anytime. Runtime Asset Storage requires an active subscription. ## Next Limits, replacing files, deleting, and manifests. Pick the region your project streams in.
