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

 }


or

$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.

That shows a description error as “Print instruction Fail detected in decomposer.” The error code and error description are alien languages for users and even system administrators who are not familiar with Fuji Xerox error code. The error code is quite simple and easy to fix, if the job print goes to the printer but print out doesn’t come out. So, basically the print job was received by the printer, but the printer just doesn’t know what type of paper or what size to use or which tray to utilize for the print out. In some instances, this is just a paper mismatch but the error description; if using Windows 10 to print does not exactly points to what is the issue. First thing to check, is the paper size selected by the user to print. Example, if the printer configuration is A3 and A4 sizes only.
