Simply deleting data from your hard drive or memory cards is not enough to ensure that the files will not be recovered by someone with the right knowledge. When files are deleted, the space they occupied is merely marked as being available for use, so it may be some time before this data is actually overwritten. Even when data has been overwritten by saving a file in the same location, there are still tools that can be used to recover data.

Even when a drive is formatted, similar techniques and tools can be used to undelete files that you thought has been erased.
