Nearly all my folders may be seen as a detailed list.
But I have around 100 selected folders which I have programmed as large
icons.
Now it happened already 3 times in this year that suddenly Explorer
'forgets' all programmed views and shows everything as icons.
Where does Explorer save the informations about the different views?
Is there a way to restore my preferred views and not to be forced to
reprogram them quite painfully?
Does Win2K have limited number of programmable views?
Thanks for your help.
