5.4. Merging capture files
Sometimes you need to merge several capture files into one. For example this can be useful, if you
have captured simultaneously from multiple interfaces at once (e.g. using multiple instances of Eth-
ereal).
Merging capture files can be done in three ways:
• Use the menu item "Merge" from the "File" menu, to open the merge dialog, see Figure 5.3,
“The "Merge with Capture File" dialog box” . This menu item will be disabled, until you have
loaded a capture file.
• Use drag-and-drop to drop multiple files on the main window. Ethereal will try to merge the
packets in chronological order from the dropped files into a newly created temporary file. If you
drop only a single file, it will simply replace a (maybe) existing one.
• Use the mergecap tool, which is a command line tool to merge capture files. This tool provides
the most options to merge capture files, see
Section C.6, “mergecap: Merging multiple capture
files into one ” .
5.4.1. The "Merge with Capture File" dialog box
This dialog box let you select a file to be merged into the currently loaded file.
Note!
If your current data wasn't saved before, you will be asked to save it first, before this
dialog box is shown.
