I need to get all the files including the files present in the subfolders that belong to a particular type.
I am doing something like this, using Get-ChildItem:
Really annoying thing in PS 5, where $_ won't be the full path within foreach. These are the string versions of FileInfo and DirectoryInfo objects. For some reason a wildcard in the path fixes it, or use Powershell 6 or 7. You can also pipe to get-item in the middle.
Get-ChildItem -path C:\WINDOWS\System32\*.txt -Recurse | foreach { "$_" }
Get-ChildItem -path C:\WINDOWS\System32 -Recurse | get-item | foreach { "$_" }
This seems to have been an issue with .Net that got resolved in .Net Core (Powershell 7): Stringification behavior of FileInfo / Directory instances has changed since v6.0.2 #7132
