Hi I'm trying to rename multiple files and folder that are in the following format:
there are multiple files with the same format in the following folders as welll

Chan12_Sitting height ratio || id-1071_CAD
DIAGRAM_Type 2 diabetes || id-976_CAD

to
Chan12_id-1071; and
DIAGRAM_id-976

I'm not sure if I understand you correctly but if those are file names, you could do something like this

original_names <- list.files(pattern="_CAD")
new_names <- paste0(str_extract(original_names, "^.+?_"),
                    str_extract(original_names, "id.+(?=_CAD)"))
file.rename(original_names, new_names)

Thanks! it worked perfectly

If your question's been answered (even by you!), would you mind choosing a solution? It helps other people see which questions still need help, or find solutions if they have similar problems. Here’s how to do it:

FAQ: How do I mark a solution?

If your question has been answered, don't forget to mark the solution! How do I mark a solution? Find the reply you want to mark as the solution and look for the row of small gray icons at the bottom of that reply. Click the one that looks like a box with a checkmark in it: [image] Hovering over the mark solution button shows the label, "Select if this reply solves the problem". If you don't see the mark solution button, try clicking the three dots button ( ••• ) to expand the full set of options. When a solution is chosen, the icon turns green and the hover label changes to: "Unselect if this reply no longer solves the problem". Success! [solution_reply_author] …
