How to restore lost files/Emails/photos that emptied from Trash Bin?
What really happens after you empty the Trash Bin on your Mac?
Clicking "Empty Trash", in fact, does not mean to erase the files themselves but instead the hard drive's directory entries for the files that were in your Mac Trash bin. This means those deleted files are still at somewhere on the hard disk and you can't see them with your naked-eyes.
Misunderstanding: you are entirely wrong if you think data can never be retrieved once it has been emptied from the Trash Bin. You can recover deleted files, photos or data as long as OS X has not re-used the directory and cataloged the information yet. Amazing! Isn't it?
The reason is very simple: The space that the files used to occupy is now free space and available for re-use. The information that included all your files and data is still there and recoverable. Sometimes, if the file you deleted is very small, it might not be overwritten for a while until another equally small-size file is written to the drive. As long as you make sure the data lost area has not been occupied, there are a great chance that lost data can be retrieved.
First step: Stop Using Your Mac Now!
If you don't stop writing new data to you Mac computer, this "free space" will be overwritten eventually. When that happens depends really on a lot of things, such as how this free space is distributed over the hard drive etc....
If you continue using your Mac computer, every hour that goes by, you significantly increase the risk that the files you want to recover will be lost forever and overwritten. It doesn't matter if the data is an email, a Word or Excel spreadsheet - the same principle applies.
This is especially true if you are currently running low on disk space. The Mac OS X overwrites this little free space very quickly with temp files. If you want to recover files from the Trash - stop using your Mac right now. Your best chance of recovering a file deleted from Trash Bin intact is to stop using your Mac immediately.
