Capture file location

Hello,
I just gor a hEX S an i try to configure it as some kind of TAP. I already kow how to stream captured packets to another computer running wireshark, that’s really cool. But as i want to only get captures files on demand (and the memory is quite little) so I installed a 32 gb SD card and plan to dowload files when necessary.
My question is : do you know how to save capture files on the SD card instead of the memory ? I could not find any relative infos on the forum.
Thanks in advance,
Yann

I love this product.

Assuming the SD card is mounted as disk1, just use /tool sniffer set file-name=disk1/my-file.pcap.

Thank you, this is working. It did not work before via the gui and now it works. Perfect thanks.
