My environment: Wireshark is installed in the Wireshark folder under Program Files on the C drive, and the source files are placed under the packet folder on the C drive
Instructions:
1. Open the command prompt as an administrator
2. Use the cd command to open the path where Wireshark is located
3. Use the mergecap command to merge files
Note:
①If you do not write the specific target address and write the generated file name directly, the merged file will be in the Wireshark installation directory
②The "*" symbol is a wildcard
③The command entered in the command prompt cannot contain Chinese, otherwise an error will be reported
The above method of use is personally tested, if you have any questions, welcome to communicate
