When Windows goes to delete a file, it goes into its file system (FAT or NTFS) and removes the pointers to the file you want to delete. In this way the operating system can no longer locate it. However, that's the end of the deletion process for Windows. The fact remains that every byte of the file continues to reside on the drive until it's overwritten. During that time, its contents can be recovered. FileVac, on the other hand, will not only delete the file pointers from the file system, but will then overwrite the contents of the file with a pattern of 1's and 0's (ones and zeroes), eradicating it completely, insuring it's unrecoverable.

The 'recycle bin' is really just a storage area. Files that are "deleted" are really just moved into that storage area. When you empty the recycle bin, the files are marked as deleted.
What actually happens is the first character of the filename is changed into a question mark, which indicates to the operating system that it is free space and available for use. If a write is done (a new file created) to the filesystem after that, it is possible that whatever was 'deleted' can be overwritten at that point.
Certain utilities (such as Norton) allow you to "undelete" those files by changing the first character of the deleted filename back to a regular character (like a,b,c, etc.).
Certain other utilities allow you to overwrite (or wipe) deleted files with a pattern (all ones (1), all zeros (0), or alternating (1,0,1,0)). If you want to do government level wiping, you must overwrite the deleted files 3 times (using different patterns).

Deleting a file to the recycle bin does not move the file. It only changes how the file may be accessed, i.e., it becomes sort of hidden and not accessable by normal means.
When you delete a file and it goes to the recycle bin, the file will remain and not be over written. But when you emply the recycle bin, then those deleted files may be overwritten later. Once overwritten they are not easily recoverable. But before they are overwritten, they may be recovered.
The next step in deleting files is to 'wipe' your hard drive clean on all deleted files. Wiping overwrites any deleted files so that they may not be recovered, at least not without going to great expense.
If you sell your computer, it is a very good idea to 'wipe' your HD completely several times to be sure your private info is not longer accessable.

It remains there, just its entry is deleted from the file system. So that the disk space can be utilised for by another file.
If the disk area is re-written than its not possible to recover the deleted while otherwise the deleted file can be recovered from the disk using some data recovery tools.

It goes to oblivion, though on a computer that is still accessible by utilities and recovery software. Than again in real life we also lack the ability to make things end up as nothing to nowhere, things only transform.

Into the ether... it still resides on your HD but the file system no longer points to it so it won't know where it is. Essentially it's gone unless you go and read the disk directly.
