How to pretend that there is more space on the disk in Ubuntu?

Question

ubuntu

Good afternoon.
The bottom line is this: there is a 500 GB hard drive. There is also a 300 GB archive. Accordingly, it will not be possible to unzip it, because. no place.
The archive is divided into parts. Accordingly, they cannot be transferred to two disks (there is no other disk for unzipping 300 GB).

You need to somehow make sure that the files are physically located on two different disks, but were visible in the first one for the archiver program to work.

Answer 1

make a symlink

Answer 2

mount the additional section as a local folder, cheat symlinks / hardlinks, as already suggested.
collect several file systems into one big one using aufs.
a lot of things can be tricked.
what type is the archive?
what partitions, disks, space on file systems are available to you??
A long time ago, when the screws were small, you had to deal with something like this. There was a zip archive with a bunch of documentation. unpacked it piece by piece.
those. I selected some of the files / dirs so that they fit neatly into the free space, unpacked them.
Then I deleted the unpacked inside the zip archive - its size decreased.
and again unpacked some of the files, etc. everything worked out.
