Today is the first day that I have PSP X4 installed on a week old Win7 Home Premium laptop, for I had to let the operating system jump through some hoops to install PSP X4 in "Win Vista SP2" compatibility mode, or not get it installed at all.
Thanks for the heads up in this thread that I fortuitously stumbled across at this time. I need to mull over this new to me Auto Preserve concept with hidden folders reportedly splattered all over the computer, in addition to learning the rest of PSP.
Add edit: Upon further reflection, I realize that I first became aware of hidden User AppData files
while researching Corel's Media One thumbs indexing on my then new Vista computer in 2008 or so. Corel Media One came bundled with Corel/Ulead PhotoImpact X3.
