I have been searching for a while, but still don't know how to do this. Can anyone help? If you don't it might be more complex than a simple substring. I just came up with this script, and I did not test it. Check out this and that for more info. The PowerShell way works for me and easier to understand and change. However, got errors like rename-item : Source and destination path must be different until I changed it a bit.

And this only begins to address the kinds of command line wizardy you can get into if you want to build more complicated commands—or even batch scripts —by weaving other commands and conditionals into things.
PowerShell offers even more flexibility for renaming files in a command-line environment. The quickest way to open a PowerShell window at your desired location is to first open the folder in File Explorer.
Easy enough. But the real power in PowerShell comes from the ability to pipe commandlets together and some of the conditional switches supported by the rename-item commandlet.
Say we wanted to replace the space in those file names with an underscore so that the file names contain no spaces. We could use the following commandlet:. The -replace switch indicates that a replacement is going to happen. For example, the rename-item commandlet also offers features like a -recurse switch that can apply the commandlet to files in a folder and all folders nested inside that folder, a -force switch that can force renaming for files that are locked or otherwise unavailable, and even a -whatif switch that describes what would happen if the commandlet was executed without actually executing it.
There are countless renaming apps our there—and many of them are good—but we have two clear favorites: Bulk Rename Utility and AdvancedRenamer. Our other favorite renaming tool, AdvancedRenamer , also exposes a huge number of renaming methods, but instead of presenting them all as panels in the interface, it asks that you use a pretty simple but powerful syntax to create renaming methods.
The tool does sport a much friendlier interface and supports setting up advanced batch jobs so you can combine multiple renaming methods and apply them to large numbers of files. You can also save renaming methods you create for later use.
It also adds an incremental file number in parentheses and separated by an additional underscore. And as you can see, my files have been renamed just the way I want. AdvancedRenamer has a bit steeper learning curve than Bulk File Renamer, but the reward for that is that you get much finer control over your file names.

I'm not sure if it's because there are multiple subdirectories or if the special characters in the names of the subdirectories are affecting it.
So I've narrowed it down to the fact the subdirectories have parentheses. Is there a way around this? That's interesting.
The rename command should work for any valid directory name. Are the subdirectories only two levels deep? However, I don't think you need either a second loop or a subroutine here.
