listening all files matching with a specific filetype and the name of the file in Groovy-CodePudding

I'm trying to put in my groovy code find files in a folder with ".bak" file type and find coincidences with the name. this is my code but is dont working for me, is there a different way to do it?

import groovy.io.*

def listfiles(dir) {
    Folder = "SomeFolder"
    nameFile = "backup_2022"
    dlist = []
    flist = []
    new File(dir).eachDir {dlist << it.name }
    if(it.name.endsWith('.bak')) {
       dlist.sort()
       new File(dir).eachFile(FileType.FILES, {flist << it.name })
       flist.sort()
       return (dlist << flist).flatten()
    }
}
html_to_be_rendered = """<select id="config" name="config">"""
fs = listfiles("\\\\SERVER\\BACKUPS\\${Folder}")
fs.each { it ->
    html_to_be_rendered = """
    ${html_to_be_rendered}
    <option value="${it}">${it}</option>
"""
}
return "${html_to_be_rendered}</select>"

I tried with if (it.name.endsWith('.bak')) but it doesn't work.

Check the following.

@NonCPS
def listFiles(def path) {
     def filterBakFiles = ~/.*\.bak$/
     new File(path).traverse(type: groovy.io.FileType.FILES, nameFilter: filterBakFiles) { file ->
                        println file
                    }
}
