I’ve found something : search : jpg.*ivia-rouge

That’s great if it works for you. But note that the regex as displayed does not work as advertised, because it is missing the underscores.

For future readers of this thread, the forum gobbled the _ characters from @Claudio-Gallego’s regex. For the regex to work with the quoted data, it must be search = jpg.*_ivia-rouge_.

To get it thru the forum without Markdown being applied to text, you need to enclose small pieces of exact text in back-ticks: `_ivia-rouge_` renders as _ivia-rouge_, instead of the italicized ivia-rouge that was seen without the proper Markdown. The PREVIEW window shows this. If you want to see more of the preview window at a time, hit the big black-circled ^ above the COMPOSE window.

This forum is formatted using Markdown, with a help link buried on the little grey ? in the COMPOSE window/pane when writing your post. For more about how to use Markdown in this forum, please see @Scott-Sumner’s post in the “how to markdown code on this forum” topic, and my updates near the end. It is very important that you use these formatting tips – using single backtick marks around small snippets, and using code-quoting for pasting multiple lines from your example data files – because otherwise, the forum will change normal quotes ("") to curly “smart” quotes (“”), will change hyphens to dashes, will sometimes hide asterisks (or if your text is c:\folder\*.txt, it will show up as c:\folder*.txt, missing the backslash). If you want to clearly communicate your text data to us, you need to properly format it.

search : jpg.*ivia-rouge
replace : jpg

With the “regular expression” mode activated.

In fact, you need to put a dot . before the *

Bring up the Replace window (ctrl+h).
Find what box: \d+_ivia-rouge_
