# How Do I Upload Local Files to a Notebook Instance?

- Small files (files smaller than 100 MB)

  Open a notebook instance and click Upload in the upper right corner to upload a local file to the notebook instance.

- Large files (files larger than 100 MB)

  You are advised to use OBS to upload large files. Use OBS Browser to upload a local file to an OBS bucket and use ModelArts SDKs to download the file from OBS to a notebook instance.

  To upload files using OBS Browser, refer to Uploading a File.

  To use ModelArts SDKs to download files from OBS to a notebook instance, refer to Downloading a File from OBS.

- Folders

  Compress a folder into a package and upload the package in the same way as uploading a large file. After the package is uploaded to a notebook instance, decompress it on the Terminal page.
