Get-Help

Get-Children

Gets items in a specified location. To list the folders in my drive C, I will run the command below:

Get-ChildItem c:\

This will list all the top-level folders. To list all files, folders include sub-folders use the -Recurse parameter.

Copy-Item and Move-Item

You could use the Get-ChildItem Cmdlet to list items in a folder, then pipe the result to Copy-Item Cmdlet to copy the items to a new location. The command below will do the job:

Get-ChildItem C:\Dropbox | Copy-Item -Destination C:\NewFolder

The above PowerShell command will only copy the top-level folders and files - it will NOT copy sub-folders and files. To copy all files and folders including sub-folders, include the -Recurse parameter in the Get-ChildItem command as shown below:

Get-ChildItem C:\Dropbox -Recurse | Copy-Item -Destination C:\NewFolder

While the Copy-Item Cmdlet copies items from one location to another the Move-Item Cmdlet moves the item.

RemoveItem

NewItem

New-Item can be used to create files, folders and registry keys and entries. The command below creates a text file called weekly_file.txt in c:\logfiles folder:

New-Item -Path c:\logfiles -Name weekly_file.tx

RenameItem

Rename-Item Cmdlet is used to rename things in Windows. This Cmdlet can rename files, folders and registry keys. This command will rename weekly_file.txt to monthly_file.txt

Rename-Item -Path C:\logfiles\weekly_file.txt -NewName monthly_file.txt

Export-Csv

Export-Csv converts a set of string into CSV and saves in a file. This Cmdlet is very important in reporting.
