I am trying to zip files in the directory which is around 300 - 400 MB and it’s taking more than 15 mins to finish. Initially I was using custom function written using ZipFile package. I have tried using Base.zip which isn’t helpful and even tried zip\_files method from ZipStreams package. This was working fine but zipped file will be having sub-directories if input path provided consists of sub-directories. I have tried to use zipsink as well but no luck. Any suggestions?

```julia
function zip(archive_name::String, files::Vector{Any}=String[])
    @info "Zip all files"
    isempty(files) && return
    w = ZipFile.Writer(archive_name)
    for file in files
        @show file
        ff = split(file, "/")
        ff= length(ff) > 3 ? ff[4] : ff[3]
        f = ZipFile.addfile(w, ff, method=ZipFile.Deflate)
        write(f, read(file, String))
    end
    close(w)
end

```
