在目录中递归列出不需要的文件 - Powershell

Question

I am trying to make a Powershell script that will display a list of files and folders in a directory('s) while not displaying a specific folder and a file.

I have a bunch of directories on the C:\\ that have a folder "DATA" and a "Setup.ini" file within them. Every once in a while people go into the data folder and make copies and then place those copies of files and directories right inside of the main directory with the "DATA" and ".ini" files. Then at the end of each month, I normally need to go through each of these directories and delete anything that is not the "DATA" folder and ".ini" file.

Get-ChildItem -Recurse "C:\TestDir" -Exclude 'Setup.ini' |  Where-Object { $_.FullName -notmatch 'Data'}

This seems to sort of work and is what I have been using this month. It runs really slow. I also noticed that one of the Directories had 2 extra folders and a zip file within it. The script only showed one of the folders and didn't show the zip file either.

I have tried adding other things to this code, but when I do that it begins showing me data inside of the "DATA" folder which I don't want.

Any idea what I could be doing wrong or ways to make this run quicker? I think it is taking about 7-10mins to run through 113 directories.

Thank you!

Expand the -Exclude and drop the Where-Object:

Get-ChildItem -Recurse "C:\TestDir" -Exclude 'Setup.ini','Data'
