regular expression to filter and read files with specific names

Question

I need to read a directory containing a number of csv files . I need to read ONLY those files such as : ABC*.csv or XYZ*.csv

Was trying as per this link here However when I tried it in postman it gave no results : ^(ABC|XYZ).*?\\.csv$")

I know this is a very simple check but am struggling with it ...

Edit1 : This is a simple Java application and does not involve R ( linked question )

Edit2 : here is the screenprint of what I am trying in notepad++

What's your actual Java code? Your `^(ABC|XYZ).*?\\.csv$")` has an unbalanced quote and parenthesis. — blhsing, Mar 08 '23 at 05:35
I think there are pattern errors on your regex, try `^(ABC|XYZ).*?\.csv$` instead — dinhit, Mar 08 '23 at 06:54

The Filters input box does not support regular expressions.

The Filters list is a space-separated list of wildcard expressions that cmd.exe can understand, like *.doc foo.*.

So in your case you would want to enter:

ABC*.csv XYZ*.csv
