There are various ISOs available for download relating to SLES15 SP1 so 30% could mean MBs or GBs.

In addition to Malcolm's questions, which OS are you using and where are you trying to save the file(s) to? Perhaps the OS and/or download method you're using uses a temporary directory before the file is saved (moved) to the required download location and the temporary directory doesn't have enough free space?
