Universal folder behavior

I work with a lot of jpgs and picture files and would like all my folders to
default to medium thumbs or at least be able to set a folder the way I want
it and have it stay that way. Every time I open a folder it defaults back to
whatever..Also I Have a site where I have to link to multiple files from a
same location on my computer and I have to retype the path over and over to
the location every time I want to link a file. Is there a way to set a path
to open automatically to the same path previously used?
