+
+## Multipart upload/download configuration
+
+If you need to upload and download large objects (typically larger than 5GB) you need to configure so-called multipart uploads/downloads. A large object is divided into multiple parts and then uploaded/downloaded. This functionality can also optimize the data throughput. On the data storage system are the objects represented as one object again.
+
+Open the tool S3 Browser and then click in the main menu on **1. Tools** and then on **2. Options**.
+

+Then click on the bookmark **1. General**. Then tick the box **2. Enable multipart uploads** and define the `part` size for upload. Then tick the box **3. Enable multipart downloads** and define the `part` size for download. In the end, click on the button **4. Save changes**.
