Rename multiple files in a folder, add a prefix (Windows)

Question

I\'d like to batch rename files in a folder, prefixing the folder\'s name into the new names. i.e. files in C:\\house chores\\ will all be renamed house chore

Answer 1

The problem with the two Powershell answers here is that the prefix can end up being duplicated since the script will potentially run over the file both before and after it has been renamed, depending on the directory being resorted as the renaming process runs. To get around this, simply use the -Exclude option:

Get-ChildItem -Exclude "house chores-*" | rename-item -NewName { "house chores-" + $_.Name }

This will prevent the process from renaming any one file more than once.
