PowerShell Copy Specific File Extension

PowerShell Code snippet to copy files with a particular extension.

$extension = ('.pdf', '.docx', '.txt')

Gci d:\WorkFolder $_ | Where-Object {

  $extension -contains $_.Extension

 } | % {Copy-Item $_.FullName d:\mix_backup}

To read files with specified filename extension.

$extension = ('.pdf', '.docx', '.txt')

Dir d:\WorkFolder $_ | Where-Object {

  $extension -contains $_.Extension



$extension = ('.pdf', '.docx', '.txt')

Gci d:\WorkFolder $_ | Where-Object {

  $extension -contains $_.Extension

 } | % {write-host $_.FullName }

Copying files with the long path will result to an error.

Robocopy a command line tool is able to copy files exceeding 256 characters.

Below is the modified code that uses robocopy to copy files with long paths.

Do not interchange source and destination when using robocopy, the files will be overwritten.

$extension = ('.pdf', '.jpg', '.txt')
gci d:\WorkFolder $_ | Where-Object {
  $extension -contains $_.Extension
 } | % { robocopy /s d:\WorkFolder d:\xtra_copy $_.Name }

Source: D:\WorkFolder
Destination: D:\xtra_copy

Change the source and destination to your own path. Please make sure that paths are not reversed or interchanged.

If paths are swap there is a high risk of data corruption or loss of data.

Copy a single file using robocopy

Copy a single file using robocopy from a local folder to a shared folder on the network.
A simple rule of thumb before any disaster strike, don't interchange the source and the destination.

If source and destination is mistakenly reverse, files might get overwritten. To avoid any loss of data do a test with a dummy file to ensure things work perfectly.
Robocopy [source][destination]   [file to be copied]
robocopy c:\local_c_folder  \\PC_network\shared_folder   file_to_be_copied_xx.txt
The command will be completed successfully provided the network access right has no issues.

Robocopy works quite good on large files. A simple copy or xcopy command will also work but the speed might vary.

Robocopy is free it can be accessed from command line. No need to install the resource kit tool if the operating system is Windows 7 or newer version.
