hi. when we export http objects the name and format of exported objects have problem. for example i sus this command for exporting object:

tshark -r test.pcap --export-object http, outputpathname

but in the output folder the name of objects are like:

object3508.text%2ftxt
object3509.image%2fjpeg
object3510.text%2ftxt
object3511.image%2fjpeg
