Default [Q] How to extract a spec lang from an all-lang file?

Hi all,

in another forum the following question was asked:

I successfully installed my language file (Hebrew) with the "all language" file I just moved into "windows" directory. Thing is, like you wrote yourself in the readme file, this is a big file, and I use it to support only one language. Do you know about a way to 'isolate' this only lang. from this big file? Only to install the lang. that I need, not all the others?

Can you show a solution, how to accomplish this? TIA
