Mounting split files

[cacamama]

Split files are annoying. Having to merge them by rewriting all the data into a separate file is time consuming and I/O intensive. Would it be possible to either
1) mount split files as a virtual file/drive
2) join them by modifying mft entries, i.e. tack a part to the end the previous file ?

To better clarify the second approach, would it be easy to merge two files by connecting them on the mft?

Mounting the split files as a virtual file/drive is possible.

AFAIK, merging the two mft entries would only be possible if the first file is aligned to the NTFS allocation unit size (4096 bytes by default).

Well, mounting as a virtual file is the simplest option I guess, if only I were proficient enough to write such a piece of software =(
This would be easier to accomplish on linux, right?

I think so too.

Yes.
