Hi Community,

I recently needed to interrogate some folders/sub-folders to retrieve filenames using cache object script(COS) and I implemented it in the following way.

ClassMethod ListDir(
               path = "",
               wildchar = "*",
               recursive As %String(VALUELIST=",y,n") = "y",
               ByRef dirlist)
{
               i path'=""{
                              i ##class(%File).DirectoryExists(path){
                                             s rs=##class(%ResultSet).%New("%File:FileSet")
                                             s sc=rs.
