As our friend Everton asked, ignore .dll and .vdf extensions, he made a mistake saying .vtf

Hello @KadabraZz ,

This configuration to ignore file extension can make in own app.

Open the file "appsettings.json" in local folder installation and change the values in key "IgnoreAaddonsExtensionsOnDeleting" and put the value, if adding value, don't forget of put a ";" in values, see this example:

{
  "AppConfiguration": {
    "TemporaryDownloadFolder": "Temp",
    "DownloadListUrl": "https://raw.githubusercontent.com/mchomem/Left4DeadAddonsDownloader.Data/master/DataSource",
    "Left4DeadAddonsFolder": "C:\\Program Files (x86)\\Steam\\steamapps\\common\\left 4 dead\\left4dead\\addons",
    "Method": "web", /*"web" - search from web site. "file" - search on local disk, on same level from executable. */
    "FileList": "downloads.json",
    "IgnoreAaddonsExtensionsOnDeleting": "dll;vtf"
  },
  "Credential": {
    "Enabled": false, /* true = requires credentials or false = does not require credentials. */
    "User": "",
    "Password": ""
  }
}

Please, give feedback about this.
