How to move characters from the end forward?

[janus]

Hello,
I am trying to figure out how I can move characters (or a string of characters, in this case the year in a date) from the end forward to a specified position but counted from the end and then move this new date completely behind the first word...?

I have a lot of files with this format:
AAA BBB CCC DDD ... MM DD YYYY.xyz

I would like to a) first move the YYYY in front of the MM DD and b) then (or simultaneously if possible?) move the whole YYYY MM DD set behind AAA.
The end result should look like this: AAA YYYY MM DD BBB CCC DDD ... .xyz

The problem is that I might be an experienced user but NOT a programmer...
Any help in resolving this question would be very much appreciated.

Hi, is there always a space between AAA and BBB, and is that always the first space in the file name?
Are there no spaces present in ... ?
If the file has a constant naming pattern, moving can de done with RegEx.

For the example, RegEx(1) could use a "Match" and "Replace" something like...
^(.+? )(.*)( \d\d \d\d )(\d\d\d\d)$
\1\4\3\2

If wanting that extra space at the end, can just add one to the end of your "Replace".

Hi Admin & Luuk
thank you for the assistance.

Luuk:
That RegEx solution looks very promising... I will test it out.

Admin:
Yes, there is always a space between AAA and BBB and the other words (AAA BBB CCC ...)
'...' is a just placeholder for n other words.

On the topic of RegEx, I have to say that I don't know what that even is but it looks interesting and I would like to learn a little bit more about it.
Is there a recommended tutorial for rookies? "RegEx for Dummies" or something like that? Youtube videos?
Thank you again.

On the other hand, after watching just a 2 minute video about RegEx it would probably be better if there were an AI solution that could help users like me...?
