Storing Assets outside of the content browser

Is there a way to access a library of content outside of a project? I have about 50GB of materials. I have a very large library of material instances that refer to one master material. Any help would be nice.

You can migrate assets to a blank project. You can backup the whole original project as well as the blank one with then the migrated assets both as a zip,rar,7z or other archiver file. Just compress the main folder/directory of the project along with all of its sub-folders/sub-directories.
