regex - How to rename multiple files at once by removing a varying part in the file name on Windows? -

I have a folder that contains 500+ files, which are with filenames ending in a string. Example:
1X 203.bmp
2x203.bmp
1086 203. BMP
25G203.bmp

How can I change the name in all the files, is it extracting the "203" string from the file names? Files should be in such a way after renaming ..

1X.bmp
2X.bmp
1086.bmp
25G.bmp

Since you are running on Windows, you can take advantage of PowerShell:

  dir | Rename-item-newname {$ _. Name -ireplace '(. +?) 203 \ .bmp $', '$ 1.bmp'}  

Description

  Dior => List of contents of the current directory = & gt; Change each next element to the next command - item = & gt; Send. Rename an element in a Windows PowerShell provider - namespaceject -newname = & gt; Specify the name of the named file {$ _ = & gt; Indicates an object representing the actual file .name = & gt; Automatic Variable-Property named after Nasthat = & gt; Replace an Insensitive '(. +?) 203 \ .bmp $' = & gt; The desired file here is '$ 1.bmp' = & gt; Comes to regex to match. Replacement string}  

You have to run this command inside the power shell. Here are the ways to start:

Then Cd alt = "switch to a directory containing files named from the powerhail window">
