The option to enable compression in capture options is now present and is the default when non-Napatech adapters are selected.

Enabling compression switches the file format to .npkt since it is the only format that supports it. It’s also possible to save in .npkt format without compression enabled by adding the .npkt extension to the packet file name. Changing to other formats that don’t support compression (.pkt, .pcap, or .pcapng) is disallowed when the check box is selected.

Compression is fully supported for LiveFlow captures which save to multiple files simultaneously.
