Here s my super cool version BECAUSE IT HAS A PROGRESS BAR  -   Which is a completely useless feature  I know  but it still looks cool  m   m    webclient   New-Object System Net WebClient Register-ObjectEvent -InputObject  webclient -EventName  UploadProgressChanged  -Action   Write-Progress -Activity  Upload progress     -Status  Uploading  -PercentComplete  EventArgs ProgressPercentage    gt   null   File    filename zip   ftp    ftp   user password server filename zip   uri   New-Object System Uri  ftp  try       webclient UploadFileAsync  uri   File    catch   Net WebException        Write-Host    Exception ToString   -foregroundcolor red   while   webclient IsBusy    continue     PS  Helps a lot  when I m wondering  did it stop working  or is it just my slow ASDL connection

I m not gonna claim that this is more elegant than the highest-voted solution   but this is cool  well  at least in my mind LOL  in its own way    server    ftp lolcats com   filelist    file1 txt file2 txt       open  server user  user  password binary   cd  dir            filelist split            put        n       ftp -i -in   As you can see  it uses that dinky built-in windows FTP client   Much shorter and straightforward  too   Yes  I ve actually used this and it works

Easiest way The most trivial way to upload a binary file to an FTP server using PowerShell is using WebClient UploadFile   client   New-Object System Net WebClient  client Credentials   New-Object System Net NetworkCredential  quot username quot    quot password quot    client UploadFile  quot ftp   ftp example com remote path file zip quot    quot C  local path file zip quot     Advanced options If you need a greater control  that WebClient does not offer  like TLS SSL encryption  etc   use FtpWebRequest  Easy way is to just copy a FileStream to FTP stream using Stream CopyTo   request    Net WebRequest   Create  quot ftp   ftp example com remote path file zip quot    request Credentials   New-Object System Net NetworkCredential  quot username quot    quot password quot    request Method    System Net WebRequestMethods Ftp   UploadFile    fileStream    System IO File   OpenRead  quot C  local path file zip quot    ftpStream    request GetRequestStream     fileStream CopyTo  ftpStream    ftpStream Dispose    fileStream Dispose     Progress monitoring If you need to monitor an upload progress  you have to copy the contents by chunks yourself   request    Net WebRequest   Create  quot ftp   ftp example com remote path file zip quot    request Credentials   New-Object System Net NetworkCredential  quot username quot    quot password quot    request Method    System Net WebRequestMethods Ftp   UploadFile    fileStream    System IO File   OpenRead  quot C  local path file zip quot    ftpStream    request GetRequestStream     buffer   New-Object Byte   10240 while    read    fileStream Read  buffer  0   buffer Length   -gt 0         ftpStream Write  buffer  0   read       pct     fileStream Position    fileStream Length      Write-Progress           -Activity  quot Uploading quot  -Status   quot  0 P0  complete  quot  -f  pct            -PercentComplete   pct   100      ftpStream Dispose    fileStream Dispose     Uploading folder If you want to upload all files from a folder  see PowerShell Script to upload an entire folder to FTP

I recently wrote for powershell several functions for communicating with FTP  see https   github com AstralisSomnium PowerShell-No-Library-Just-Functions blob master FTPModule ps1  The second function below  you can send a whole local folder to FTP  In the module are even functions for removing   adding   reading folders and files recursively   Add-FtpFile -ftpFilePath  quot ftp   myHost com folder somewhere uploaded txt quot  -localFile  quot C  temp file txt quot  -userName  quot User quot  -password  quot pw quot  function Add-FtpFile  ftpFilePath   localFile   username   password         ftprequest   New-FtpRequest -sourceUri  ftpFilePath -method   System Net WebRequestMethods Ftp   UploadFile  -username  username -password  password     Write-Host  quot    ftpRequest Method  for     ftpRequest RequestUri   complete  quot       content    content    System IO File   ReadAllBytes  localFile       ftprequest ContentLength    content Length      requestStream    ftprequest GetRequestStream        requestStream Write  content  0   content Length       requestStream Close        requestStream Dispose       Add-FtpFolderWithFiles -sourceFolder  quot C  temp  quot  -destinationFolder  quot ftp   myHost com folder somewhere  quot  -userName  quot User quot  -password  quot pw quot  function Add-FtpFolderWithFiles  sourceFolder   destinationFolder   userName   password        Add-FtpDirectory  destinationFolder  userName  password      files   Get-ChildItem  sourceFolder -File     foreach  file in  files             uploadUrl   quot  destinationFolder    file Name  quot          Add-FtpFile -ftpFilePath  uploadUrl -localFile  file FullName -username  userName -password  password           Add-FtpFolderWithFilesRecursive -sourceFolder  quot C  temp  quot  -destinationFolder  quot ftp   myHost com folder  quot  -userName  quot User quot  -password  quot pw quot  function Add-FtpFolderWithFilesRecursive  sourceFolder   destinationFolder   userName   password        Add-FtpFolderWithFiles -sourceFolder  sourceFolder -destinationFolder  destinationFolder -userName  userName -password  password      subDirectories   Get-ChildItem  sourceFolder -Directory      fromUri   new-object System Uri  sourceFolder      foreach  subDirectory in  subDirectories             toUri    new-object System Uri  subDirectory FullName           relativeUrl    fromUri MakeRelativeUri  toUri           relativePath    System Uri   UnescapeDataString  relativeUrl ToString             lastFolder    relativePath Substring  relativePath LastIndexOf  quot   quot   1          Add-FtpFolderWithFilesRecursive -sourceFolder  subDirectory FullName -destinationFolder  quot  destinationFolder  lastFolder quot  -userName  userName -password  password

I am not sure you can 100  bullet proof the script from not hanging or crashing  as there are things outside your control  what if the server loses power mid-upload   - but this should provide a solid foundation for getting you started     create the FtpWebRequest and configure it  ftp    System Net FtpWebRequest   Create  ftp   localhost me png    ftp    System Net FtpWebRequest  ftp  ftp Method    System Net WebRequestMethods Ftp   UploadFile  ftp Credentials   new-object System Net NetworkCredential  anonymous   anonymous localhost    ftp UseBinary    true  ftp UsePassive    true   read in the file to upload as a byte array  content    System IO File   ReadAllBytes  C  me png    ftp ContentLength    content Length   get the request stream  and write the bytes into it  rs    ftp GetRequestStream    rs Write  content  0   content Length    be sure to clean up after ourselves  rs Close    rs Dispose
