Hi,

Unfortunately, GetFiles doesn’t support regex filter as the following document.

Directory.GetFiles Method (System.IO)

Can you try to use LINQ as the following, for example.

 System.IO.Directory.GetFiles(FilePaths1).Where(Function(f) System.Text.RegularExpressions.Regex.IsMatch(System.IO.Path.GetFileName(f),"(PAN|CHEQUE|GST).*.pdf|jpeg$")).ToArray

Hi,

Hope the following helps you.

System.IO.Directory.GetFiles(FilePaths1)

means to return all files in FilePaths1 folder.

.Where(Function(f) 

This means iterate the above files and filter out false item which the following expression returns

System.Text.RegularExpressions.Regex.IsMatch(System.IO.Path.GetFileName(f),"(PAN|CHEQUE|GST).*.pdf|jpeg$")).ToArray

This return true if the filename matches the regex pattern.
note: System.IO.Path.GetFileName returns just filename without directory.

As a result, we cam get files as if it were to use GetFiles with regex pattern.
