A similar question to mine has been asked before - I want to be able to delete all my Google Docs at once. I used a synchronization app called Syncplicity which synced all my documents with my Google Docs. Unfortunately, due to a bug, it caused loads of errors and problems which I won't go into.
The answer to the question that was asked previously was to
move a collection to the bin which also moves all documents within said collection
Unfortunately none of my documents are in a collection. I have literally thousands of documents and either bulk selecting the documents page by page and adding them to a category or to the trash bin will take ages. Is there a way to say I want all my documents deleted? I thought of closing my Google Docs account, but I do want to use Google Docs in the future and apparently Google doesn't properly delete the Docs straight away anyway.
