# Function: uploadFiles()

> **uploadFiles**(`instance`, `codeVersion`, `uploads`, `deletes`, `options?`): `Promise`\<`void`\>

Defined in: [packages/b2c-tooling-sdk/src/operations/code/upload-files.ts:76](https://github.com/SalesforceCommerceCloud/b2c-developer-tooling/blob/e7c16f1ae423da0aa47b3e10be88f9770b53619b/packages/b2c-tooling-sdk/src/operations/code/upload-files.ts#L76)

Uploads and deletes files on an instance via WebDAV.

the VS Code extension. It:
1. Filters out non-existent upload files
2. Creates a ZIP archive of upload files
3. Uploads via WebDAV PUT and unzips on server
4. Deletes files (skipping any that were also uploaded in the same batch)
