Hi all.
I want to copy my Cygwin installation on my SD card. Since it's formed
by many small files, and my flash memory performance is very poor with
such files, I was wondering if there is some way to mount a tar file, or
something like, even if in read-only way, searching in the archive if
the file is not found in the "normal" directory and writing everything
in the latter.
Thank you,

An ISO-9660 image is sort of like a tar file, but with some extra overhead. It sounds like you are trying to do something like Knoppix. They use a compressed read-only filesystem for the base image, combined with a special read/write filesystem (based on symlinks, I think) that holds actual file data only for changed files.
Doing this in Windows would not be easy. There are some programs around that mount ISO images as a virtual filesystem. But, if you have to install extra support software, what is the point of installing Cygwin on an SD card? If you want a portable Cygwin, why not put most of it onto a CD?
