Hi All, Sorry for my English I searched the forum a function like that, and not found, indeed, there are many topics request regarding all this function, and I have done this, I did not know what name to put them RegEnumKeyToArray or RegListToArray or ect ect in the end I chose _RegEnumKeyValEx (_RegEnumKeyEx & _RegEnumValEx), the function does almost everything (also includes $sFilter as the >_FileListToArrayEx), and works really fast too   #include-once ; #UDF# =================
