Sorry, yes, meant lossless. I'm looking to have SS4.3 convert from 352lossless to 352atrac when transferring to the zx1. I'm okay with quality step down in favor of better space utilization. The songs that are not greyed out convert fine albeit slow. All of the tracks are on an external drive for which I fixed both permissions and ownership. I can write to the drive, delete other content from it, however, nothing i do in regedit or otherwise returns the tracks to non-grey status in SS4.3. I'm looking to maintain the playlist / architecture of SS so drag / drop isn't for me at this time. Not sure I understand what you mean by the File Conversion Tool? All my files were uploaded as Lossless atrac. Thanks again!
