Instead of For Each File with an embedded If, you could just use an expression to get all the files you want. Assign the result to a variable and then For Each through that variable, with the Move File activity inside it, using currentItem.FullName to designate the filename to move.
Create yourFilesVar as IEnumerable(of FileInfo)
Assign yourFilesVar = New System.IO.DirectoryInfo(*folderpath*).GetFiles("*0HA_280*").Where(Function(f) f.Extension.ToUpper = ".XLSX" OR f.Extension.ToUpper = ".TXT")
