In this post we will see how to copy and move files and folders selectively with PowerShell. We are going to use Copy-Item cmdlet with a few switch parameters for copying files. Similarly, with Move-Item cmdlet, you can use all the examples below for moving the desired files.
1. Copy File with Copy-Item cmdlet
Copy-Item C:\Source\Test.txt C:\Destination
This simple script will copy “Test.txt” file from the “Source” directory to “Destination” directory.
2. Recursively Copy Sub-Directories with Copy-Item cmdlet
Copy-Item C:\Source\* C:\Destination -recurse
-recurse parameter recursively searches for all files and folders within “Source” directory.
3. Copy Files from Multiple Directories and Merge into One Folder
Copy-Item C:\Source\A\*, C:\Source\B\* C:\Destination
This would create a flat folder structure by copying all files from directory “A” and “B” and paste the files into “Destination” folder.
4. Exclude Particular File Type from Copy
Copy-Item C:\Source\ C:\Destination -recurse -exclude *.txt
This would exclude all Text files, including sub-directories, from being copied.
5. Exclude a Particular File Type with Specific Name from Copy operation
Copy-Item C:\Source\ C:\Destination -recurse -exclude [a-d]*.txt
This would exclude all “txt” files that matches wild card pattern [a-d].
6. Copy Files Based on Filename Prefix
Copy-Item C:\Source C:\Destination -filter DSC_* -recurse
This would copy only those files which start with prefix “DSC_”
7. Copy Files Containing Particular Keyword
Get-ChildItem C:\Source -recurse -filter '*DSC*.jpg' | Copy-Item -destination C:\Destination
This would copy all files which has “DSC” anywhere in their name and is of type “JPG.”
8. Copy Files Without Preserving Directory Structure
We can perform more complex copy and move operations by piping the results of the Get-ChildItem cmdlet to the Copy-Item and Move-Item cmdlets.
Get-ChildItem C:\Source -recurse -force -filter "Aa*" | Copy-Item C:\Destination
This would create a flat folder structure by copying all files starting with “Aa” to the root of “Destination” directory.
Some optional parameters:
–whatif: With this parameter you can verify the result of a particular copy or move operation without actually executing it. Files are not moved until you run the cmdlet by removing–whatifparameter.-verbose: With this parameter you can view the output of each file operation in the console.-force: By default copy and move operation will not overwrite a file. With this parameter you can force the override of an existing item or a read-only system file.
