# Chunk Upload

The Upload enables you to upload chunks of files from local file systems to dedicated server handlers which are configured to receive them.

To enable chunk upload, set the `async-chunk-side` property to `true`. Each request sends a separate file blob and additional string metadata to the server. This metadata is in a `stringified` JSON format and contains the `chunkIndex`, `contentType`, `totalFileSize`, `totalChunks`, and `uploadUid` properties. These properties enable the validation and combination of the files on the server. The response also returns a JSON object with the `uploaded` and `fileUid` properties which notify the client what the next chunk is.
