The Cloud Service Foundation data upload process supports the upload into single target (table or maintenance object) from multiple data files. For example, instead of extracting a large Payment table into a single payment.csv file, you can split the extract into payment1.csv, payment2.csv, payment3.csv, and so on.

It is recommended to keep the file size under 2 gigabytes. The number of files is unlimited. Naming conventions apply. See the online help for more details.
