I'm pretty sure there's no way to use a 'temporary' filesystem that is never written to disk but just to the RAM while the application needs it. So is there a way to add it? The reason for this is that there are many applications (the AS3 Personal Firewall being one example) that write to the %temp% folder (e.g: C:\Windows\Temp) prior to execution and need that file. They delete it when they are closed.
This can be redirected, of course, into a filesystem, but not in a temporary RAM/memory location. But what about read-only media (such as a CD) or a flash USB with disabled writing? It won't work (the app won't load in most cases), so is there a way to redirect it into RAMdisk or memory, just like the registry?
There are [PortableRegExclude] and the respective include in registry, so we could have something similar to Filesystems. For example the app could write its 'temp' stuff into a temporary RAMdisk and be 100% portable and not touching any media (so it'll work from a read-only media). What do you think?
EDIT: You could, for example, put something like this:
[SpecialFolders]
%temp%=:RAM
(note the ':' which is invalid in Windows Filesystems)
