Use OBS to upload large files. To do so, use OBS Browser to upload a local file to an OBS bucket and use ModelArts SDK to download the file from OBS to a notebook instance.
For details about how to use ModelArts SDK or MoXing to download files from OBS, see How Do I Upload a File from a Notebook Instance to OBS or Download a File from OBS to a Notebook Instance?
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.
unzip xxx.zip # Directly decompress the package in the path where the package is stored.
For more details, search for the decompression command in mainstream search engines.
