What is the right command to repack the PAK archives?

[AEBus]

Hello, what is the right command to repack the PAK archives?
When I try this kind of command: LucaSystemTools -t pak -m import -f wrk -o rdy pops up a bunch of errors.

D:\wrk\LucaSystemTool>LucaSystemTools -t pak -m import -f wrk -o rdy

Using a bunch lb_en

I am confused by the error Could not find a part of the path 'D:\wrk\LucaSystemTool\wrk\SCRIPT_unpacked\SEEN0513'.
There is no such folder SCRIPT_unpacked but SCRIPT .PAK _unpacked

[AEBus]

Ow, when i replaced

        public static void Pack(string file)
        {
            Encoding.RegisterProvider(CodePagesEncodingProvider.Instance);
            string out_file = Path.Combine(Path.GetDirectoryName(file), Path.GetFileNameWithoutExtension(file));

with

        public static void Pack(string file)
        {
            Encoding.RegisterProvider(CodePagesEncodingProvider.Instance);
            string out_file = Path.Combine(Path.GetDirectoryName(file), Path.GetFileName(file));

In PakTools.cs, then renamed SCRIPT.PAK.pakhead into SCRIPT.PAK, a command LucaSystemTools -t pak -m import -f SCRIPT.PAK work without errors.
When i need repack a multiple files, i use a command LucaSystemTools -t pak -m import -f wrk -o wrk, then all PAK files in folder repacked.
