I at wits end trying to rename NTFS files that have technically legal, but problematic multiple periods in my Windows 2012 Server share

Files are dropped in a share that look like this:

THIS.IS.THE.FILE.NAME.20150102

THIS.IS.THE.FILE.NAME.20150103 (etc)

(Note: the date in the extension does not match the current date or anything like that.)

I would like to use Windows command shell end with files named simply like this:

20150102.CSV or FILE_20150102.CSV

20150103.CSV or FILE_20150103.CSV

I have tried various combinations of the rename command with various permutations of Asterisks * and/or ??? wildcards, with and without quotes. However, at most I end up deleting off the "extension" containing the date.

Ideally, there is a form of the rename command I just haven't used that can do the trick simply at the command prompt (or batch) without PowerShell.

However, if there is a complete explanation of a simple Powershell command/script I can use within Task Scheduler, I could give that a go. As noted, I am using Win Server 2012 (in its default config)

However, I am specifically unable to use any 3rd party executables, no matter how useful.

Thanks!

  • This is a good learning opportunity to get started with Powershell. Is there anything you've tried yet that is giving you difficulty?

I think this answer should get you most of the way to what you need.

It covers getting the extension from each file and then doing a rename.

  • No, it does not work with the complications of multiple periods, which is the heart of my issue. Basic complication is rename is plainly ugly through batch with multiple periods Jan 16, 2015 at 0:44
