How to fix this annoying problem:
By default, Windows XP will remember the view settings for the 400 most
recently used folders. After that, XP will begin overwriting the data of
the oldest folder, and its view setting will be lost. The information is
stored in the registry by two keys: ...
"
I heard SP3 removed that limit but I'm not sure; I have SP3 but don't
recall running into the limit, if I did.
I'd check the registry lines indicated and see if the 400 was still
there and change it to 4000 or 8000. No idea how high it can be set and
not screw up so I wouldn't go much over 8000, which is what developers
often use.I've seen other articles offer 2000 as a recommendation. I
used 8000 for years now when I made that mod to the registry.
As always, whenever you change a line in the registry, back up that
line of the registry first in case you need to get it back. Misakes
happen way too easily. After being backed up, clicking the *.reg file
it created will put the line back in the registry.
XP.
I don't know about how many settings. I have a tweaker that will set
it to many hundreds. That may be normal or a trick.
Tweakers can often be handy but many of them make changes to things they
don't tell you about & thus you don't know what happened in your system.
And you might not know a tweak borked something else and might never
make the connection.
Most tweaks are simply little stubs that make changes that there are
methods for already in XP. The value of tweakers is for those who don't
want to learn how to do things directly and prefer to let a program do
it for them. IMO it's much better to make the tweaks manually, document
them, and have a record for later on when you wonder if one of those
tweaks is causing an issue you might be having. Often if you take the
time to read the tweaker files (they're just text in .vbs, .reg,
whatever), you can tell which XP setting they change. Not so possible
in the larger integrated programs though, like tweakui and Norton's
optimizer, etc..
