wimlib

I would like to understand how "wimcapture --pipable" option works. Please help me in understanding better. Also let me know which is source code that I can refer for understanding --pipable option.

Is --Pipable option performing sector based capture like dd utility or file based capture?

A WIM created with the --pipable option is like a normal WIM, except some of the data is rearranged to make it possible to extract sequentially. It's still "file-based".

Also, if you're looking for more detail see write_pipable_wim() in src/write.c. There's a comment that explains the format changes that were made.
