anyone successfully convert a SACD ISO to FLAC files?

[Happy Hopping]

I go thru 1 link, it doesn't work, keep saying insert [music artist name] directory can't be created.

so I then try this video:



but I can't get that file called DSDMat Plugin

so has anyone manage to get it done? if so, any link or video that you find useful?
