|Generally speaking temporary files created by applications do not go to the recycle bin, they are just deleted. If temp files were sent to the recycle bin then the bin would fill up pretty fact with files that were of no use.|
The only difference between sending a files to the recycle bin and deleting it completely is the way the directory entry is updated. In neither case is that data actually touched. In both case it is just a metter of changing a few bytes on the hard disk.
In the case of a file going to the Recycle Bin the information in the directory is just changed to reflect its new location. In the case of a complete delete the directry entry is marked as free and the space the file uses is marked as available and it remains intact until something else comes along and overwrites it.
