On a Linux system, is there any way to concatenate a series of files into one exposed file for reading and writing while not actually taking up another N bytes of disk space? I was hoping for something like mounting these files via loopback/devmapper to accomplish this.
I have a problem where there are split binary files that can get quite large. I don't want to double my space requirements with massive disk IO just to temporarily read / write contents from these files by
cating them all together into one enormous file.
I found this project here, but it seems to have a very specific use case and also depends on perl
