Considerations when using "download"
If using "download" with FileStore (NS3), the following considerations apply.
Download operations are allowed for files up to 1.8 GB in size. Larger files would need to be downloaded through an appropriate Akamai Delivery Configuration. (Contact your Account Representative for more details.)
While there is no set maximum on the number of files that can be downloaded using this action, it is important to note that the tool is not intended for use as a “mass download” resource. If used to download a large quantity of files in a single call, you may notice performance issues, and possibly failures.
If you intend to download a large quantity of files, it is recommended that you incorporate an Akamai Delivery Configuration and incorporate Large File Optimization. (Contact you Account Representative for more details.)
