+
+You can manage files in your YepCode workspace using the `YepCodeStorage` class. This allows you to upload, list, download, and delete files easily.
+
+```js
+const { YepCodeStorage } = require('@yepcode/run');
+const fs = require('fs');
+
+const storage = new YepCodeStorage({ apiToken: '****' });
+
+// Upload a file (using Node.js stream)
+await storage.upload('path/myfile.txt', fs.createReadStream('./myfile.txt'));
+
+// List files
+const files = await storage.list();
+console.log(files);
+
+// Download a file
+const stream = await storage.download('path/myfile.txt');
+stream.pipe(fs.createWriteStream('./downloaded.txt'));
+
+// Delete a file
+await storage.delete('myfile.txt');
