powershell: remove characters in string

Question

I have a list of files in this format NameSerie.S0E1.randomcharacters.mkv where i want to remove the randomcharacters to get NameSerie.S0E1.mkv

I have the following but for this i need to know the randomcharacters which sadly are random.

#rename files
Get-ChildItem $Location | Rename-Item -NewName {$_.Name.Replace("[480p]","") }

Does someone have an idea?

Please define (in the question) what is recognizable in your string rather than what is not. Presumably the extension is always .mkv (or not???), are the dots always on the same place? Is there always a S#E# format in front of the random characters? etc. — iRon

the .mkv is always there and the rest is always formated like this. — Albin Gjoka

You could use

(.*?)[^.]+\.([^.]+)$

And replace this with

$1$2

See a demo on regex101.com.
Alternatively, you could split on the dot and glue the array back together programatically.

Try this:

#rename files
Get-ChildItem $Location | Rename-Item -NewName {$_.Name.Split(".")[0..1] -join ".$($_.Name.Split(".")[3])" }
