If I have deleted/moved/renamed folders of Photos (using Windows
Explorer) that the Photoshop File Browser had created cache entries for,
does Photoshop ever find these cache entries and remove them (or can I
manually tell PS to go clean up after itself)? If not, is there a way
to selectively find and remove these entries?

That seems like a royal pain anyway .... so I'm considering purging the
entire cache (it's 1.13GBs). I occasionally clean shop (perhaps once or
twice a year) and that involves moving, deleting, and renaming folders
(and their files), so my guess is that a lot of that 1.13 GBs is wasted
space. I have always used Windows Explorer to do this so I can
shift-delete, if need be, and bypass the recycle bin. Perhaps I should
always use the PS File Browser (from now on), but it's too late at this
point.

I have one folder - C:/Photos - that has the VAST majority of my photo
files in it - 32 GBytes. If I Purge the entire cache and then want to
rebuild it for that folder (32 GBs in 718 folders, 19,000 files), how
long might it take ... roughly (overnight, 1 hour, 2days)?

..... I assume that if I select C:/Photos and then Build Cache for all
Subfolders, that is what it will do.

Is that my best recourse? Has anyone experience with rebuilding the
cache on this scale?
