Using Swiss File Knife to Split/Join a large binary file

Here's an example of using the Swiss File Knife utility to split a large binary file;
Code:
E:\Utils>sfk split 2g e:\utils\iso\windows.iso
splitting into files of 2000000000 bytes each.
e:\utils\iso\windows.iso split into 3 files, 4600823808 total bytes.
md5 = efb0ceb1fbbd58fbe383b5b698b3fff9   [write ]
md5 = efb0ceb1fbbd58fbe383b5b698b3fff9   [verify] - OK

This split the windows.iso file into 3 pieces;
Code:
2023-08-02  17:46   2,000,000,000  windows.iso.part1
2023-08-02  17:47   2,000,000,000  windows.iso.part2
2023-08-02  17:47     600,823,808  windows.iso.part3

Now, to join them back together;
Code:
E:\...\iso>sfk join windows.iso.part1
windows.iso created from 3 files, 4600823808 total bytes.
md5 = efb0ceb1fbbd58fbe383b5b698b3fff9

Note well that an md5 hash is used when splitting/joining the file(s).

Never tried it, but I have to say: I love the name!
