rename files

[Francisco]

Fellow Notepad++ Users,

Could you please help me the the following search-and-replace problem I am having?

DESCRIBE CIRCUMSTANCES OF YOUR QUESTION

I would like to make these files available for download (or just for text viewing), but with the filenames changed—keeping only the part of the name that appears before the underscore.
Here is the data I currently have (“before” data):

“C:\contest\cvadx\2024\CW\DL8FMA_8U5QC.txt”
“C:\contest\cvadx\2024\CW\DL8UKW_8WMM6.txt”
“C:\contest\cvadx\2024\CW\DL8UKW_RMXE3.txt”
“C:\contest\cvadx\2024\CW\DM1AA_6J2IN.txt”

Here is how I would like that data to look ("after" data):

“C:\contest\cvadx\2024\CW\DL8FMA.txt”
“C:\contest\cvadx\2024\CW\DL8UKW.txt”
“C:\contest\cvadx\2024\CW\DL8UKW.txt”
“C:\contest\cvadx\2024\CW\DM1AA.txt”

very thanks
Francisco Freitas

@francisco this is a classical task for a RegEx Search/Replace.

Open Replace Dialog and select “Regular Expression” as Search Mode. At “Find what” enter ^(.*)_[^.]*. At “Replace with” enter $1. Hit “Replace All”.

You may want to have a look at https://npp-user-manual.org/docs/searching/#regular-expressions for an introduction to Regular Expression Searches. For further reading have a look at https://community.notepad-plus-plus.org/topic/15765/faq-where-to-find-regular-expressions-regex-documentation. You will find a lot of useful information and links there.

Hello, @francisco, @gerdb42 and All,

There are plenty of solutions !

The following one will ensure that the . matches newline option will not be used even it’s checked and that the Match case option is enabled even it’s not checked !

FIND (?-si)_.+(?=\.txt)

REPLACE Leave EMPTY

Best Regards,
