Hey, looking the net, I found
this
The most important in this link, I wroted donw:
Question: "Is it possible to restore a original file if it has been overwritten with a file of the same name but different size??"
One of the answers: "It is not possible without professional help, but if you were using Word, you should find a series of temp files on your HDD and if you sort them by date, you may find a copy of your old file from the last time you modified it. I have twice recently recovered files like this, one on the same day, but another that was several weeks old. (Oh joy
)
Do a file search for *.tmp and open each one that fits in your date range. I usually use ZTree for this because it lets you view the file contents then save with a doc suffix but you can achieve the same outcome in Explorer, it just takes longer. Good luck!"
I hope this can help you
Good luck!!!
