The AlexFTPS library used in the question seems to be dead  was not updated since 2011      With no external libraries  You can try to implement this without any external library  But unfortunately  neither the  NET Framework nor PowerShell have any explicit support for downloading all files in a directory  let only recursive file downloads    You have to implement that yourself    List the remote directory Iterate the entries  downloading files  and optionally recursing into subdirectories - listing them again  etc     Tricky part is to identify files from subdirectories  There s no way to do that in a portable way with the  NET framework  FtpWebRequest or WebClient   The  NET framework unfortunately does not support the MLSD command  which is the only portable way to retrieve directory listing with file attributes in FTP protocol  See also Checking if object on FTP server is file or directory   Your options are    If you know that the directory does not contain any subdirectories  use the ListDirectory method  NLST FTP command  and simply download all the  names  as files  Do an operation on a file name that is certain to fail for file and succeeds for directories  or vice versa   I e  you can try to download the  name   You may be lucky and in your specific case  you can tell a file from a directory by a file name  i e  all your files have an extension  while subdirectories do not  You use a long directory listing  LIST command   ListDirectoryDetails method  and try to parse a server-specific listing  Many FTP servers use  nix-style listing  where you identify a directory by the d at the very beginning of the entry  But many servers use a different format  The following example uses this approach  assuming the  nix format      function DownloadFtpDirectory  url   credentials   localPath         listRequest    Net WebRequest   Create  url       listRequest Method    System Net WebRequestMethods Ftp   ListDirectoryDetails      listRequest Credentials    credentials       lines   New-Object System Collections ArrayList       listResponse    listRequest GetResponse        listStream    listResponse GetResponseStream        listReader   New-Object System IO StreamReader  listStream      while    listReader EndOfStream                 line    listReader ReadLine            lines Add  line    Out-Null            listReader Dispose        listStream Dispose        listResponse Dispose        foreach   line in  lines                 tokens    line Split      9   StringSplitOptions   RemoveEmptyEntries           name    tokens 8           permissions    tokens 0            localFilePath   Join-Path  localPath  name          fileUrl     url    name           if   permissions 0  -eq  d                         if    Test-Path  localFilePath -PathType container                                 Write-Host  Creating directory  localFilePath                  New-Item  localFilePath -Type directory   Out-Null                            DownloadFtpDirectory   fileUrl         credentials  localFilePath                   else                       Write-Host  Downloading  fileUrl to  localFilePath                downloadRequest    Net WebRequest   Create  fileUrl               downloadRequest Method    System Net WebRequestMethods Ftp   DownloadFile              downloadRequest Credentials    credentials               downloadResponse    downloadRequest GetResponse                sourceStream    downloadResponse GetResponseStream                targetStream    System IO File   Create  localFilePath               buffer   New-Object byte   10240             while    read    sourceStream Read  buffer  0   buffer Length   -gt 0                                 targetStream Write  buffer  0   read                              targetStream Dispose                sourceStream Dispose                downloadResponse Dispose                       Use the function like    credentials   New-Object System Net NetworkCredential  user    mypassword     url    ftp   ftp example com directory to download   DownloadFtpDirectory  url  credentials  C  target directory    The code is translated from my C  example in C  Download all files and subdirectories through FTP     Using 3rd party library  If you want to avoid troubles with parsing the server-specific directory listing formats  use a 3rd party library that supports the MLSD command and or parsing various LIST listing formats  And ideally with a support for downloading all files from a directory or even recursive downloads   For example with WinSCP  NET assembly you can download whole directory with a single call to Session GetFiles     Load WinSCP  NET assembly Add-Type -Path  WinSCPnet dll     Setup session options  sessionOptions   New-Object WinSCP SessionOptions -Property        Protocol    WinSCP Protocol   Ftp     HostName    ftp example com      UserName    user      Password    mypassword      session   New-Object WinSCP Session  try         Connect      session Open  sessionOptions         Download files      session GetFiles   directory to download      C  target directory     Check     finally         Disconnect  clean up      session Dispose           Internally  WinSCP uses the MLSD command  if supported by the server  If not  it uses the LIST command and supports dozens of different listing formats   The Session GetFiles method is recursive by default    I m the author of WinSCP

For retrieving files  folder from FTP via powerShell I wrote some functions  you can get even hidden stuff from FTP   Example for getting all files which are not hidden in a specific folder   Get-FtpChildItem -ftpFolderPath  ftp   myHost com root leaf   -userName  User  -password  pw  -hidden  false -File   Example for getting all folders also hidden  in a specific folder   Get-FtpChildItem -ftpFolderPath ftp   myHost com root leaf   -userName  User  -password  pw  -Directory   You can just copy the functions from the following module without needing and 3rd library installing  https   github com AstralisSomnium PowerShell-No-Library-Just-Functions blob master FTPModule ps1
