One Answer:


Then it's either not a Wireshark capture file (e.g. it's text output redirected to a file), or the file got damaged (e.g. when using FTP file transfer in non-binary mode). Inspecting the file (e.g. with the file utility on Linux, or opening it with an ASCII text editor) could shed some light on the type of file it really is.

How did you copy this file from the one PC to the other ?
