The following step-by-step illustrations explain using the ASAMMDFGUI tool to merge multiple log files.
Change the software mode to Batch Processing.
Select the Concatenate option from the left panel.
Click File and open all the files to be merged; multi-selection is allowed.
Once files are opened:
Choose the concatenation settings (It is preferred to choose the output format 4.0 or above) and click concatenate; the software will merge the files and produce a single .mf4 file.
The file list can be rearranged by dragging and dropping lines. Unwanted files can be deleted by selecting them and pressing the DEL key. The file order is considered from top to bottom.
