You can join the multiple parts from the partial dumping feature, by using one of the scripts included in
Choose the correct one for the size of parts (15 parts of 2GB or 30 of 1GB) and your OS (windows or linux/macos).


Warning 1: If you have an unfinished partial dumping and want to start anew, delete the partial.idx file first.
Warning 2: When dumping the eMMC, in parts, you should not power on the switch normally and boot to Switch OS before done. Otherwise your finished backup will probably be corrupted, because Switch OS writes on your eMMC even if it seems you done nothing.
