"99% chance that you will not be able to recover your essay as it was only in ram and not saved to the HDD. But at least try this:
- Use the "Search" capability and search the C partition using find text or words in file option. Use wild cards if needed to search any/all file types and be sure to include hidden files in the search. Then search on one or two or three unique words or phrases that you used in your essay that most likely would never be expected to appear in any other file (eg, a word like "existential" or some unique date such as "Dec 1872" provided it was used in the essay. Search on the word or phrase exactly as it was typed in the essay.)
Hopefully, if the essay file is on the HDD at all, then it might be identified thru finding the unique key words."
