all those locales/language files could be in a locale/lang foler

just as they are in the doc folder .
that way makes it tidier . and easier to just delete for who will not use -to save space.

Putting them in a separate folder may be an ok idea, but you cannot remove all of them, as the tool would become unusable without at least the English strings (FarEng.lng).

yeah i left only eng ing and hlf and it works normaly . the person can in the folder select all then deselect only the one used -this is easier with them all in a folder for them .

and also those files you named fareng farpoletc ... , it would be better to name just eng , rus pol etc ; without the far . this makes it cleaner and also easier to select/filter by just typing the first letter

deleting the unused files makes it 6mb smaller for the portable version - 50 to 44 mb .

select all then deselect only the one used

Even without grouping them to a dedicated directory, CtrlAdd works just fine to select by extension.

it would be better to name just eng , rus pol etc ; without the far

But it would be harder to locate these files by filtering History. I often type e.g. fareng as a filter (and I have quite a lot other files with eng).

easier to select/filter by just typing the first letter

You can type *pol for the same effect. I doubt anyone needs to do it so often as to warrant the change.

doing manual , need to do at each new release .
i see that theres apps that do it auto , like phoenixPE PEBakery that makes some winpe customized .
in the lasts options there in finalize>Slimfast , theres the option:
-clean unused lang folders .

Try using this script. New language files do not happen often, so you can keep it up to date manually.
