|To further answer your question all deleted files are not actually moved anywhere but simply tagged as deleted or moved to the recycle bin. |
Those files that are deleted directly can be overwritten. Files sent to the recycle bin no longer show in explorer but are still intact and won't be overwritten until the threshold for recycle bin space is exceeded.
Once that happens they may not be recoverable. Before then there are many programs that can recover deleted files, even ones too big for recycle bin.
The key is whether they have been overwritten yet.
