-The list file for tsmerge can contain relative or absolute paths, but the path format differs from Windows to Linux/UNIX/MacOS (like volume paths or "/" instead of "\" to separate directories).
-The list must be a text file and describe one ts path per line.

-The concatenation made by tsmerge is not a raw (binary) concatenation, like `dd`, `cat` or `pv` would do on Linux, or `copy /b` on Windows.
-Instead, the streams have to be partially recoded, to keep its structure valid and playable. Using other software may not achieve this result.
