A couple of related questions:
1. i renamed my project root dir, due to which the "reopen recent" stopped working (couldn't find the directory). hence: is there a changeable file that contains the recently opened project names where i can modify the project dir?
2. if not, as in this case, where i just did a "open project" and it's indexing all the millions of files and setting up the project all over again, is there a way to delete the old caches which are obviously mongo-big and not going to be used anymore? or better still, does intellij have some kind of batch process that will delete old caches that haven't been updated in a certain timeframe?
