You have see my PC/laptop life saver series, but now you want to get rid a file forever, because of confidentiality or any other reasons, you don't want anyone to recover the file, ever. There are a few commercial software that can do the job, but I think the freewares that I want to introduce will be good enough to do the job.
1. File Shredder
From the publisher:
With File Shredder you can remove files from your hard drive without fear they could be recovered. There are quite a few software tools today for retrieval of deleted files under Windows OS. Those tools, often referred to as "file recovery" software, are taking advantage of shortcoming of Windows "delete" command that we all use regularly to delete files. Actually, the "delete" operation in Windows only removes bits of information from files so they appear deleted in OS. It is easy to retrieve those files using aforementioned specialized file recovery software.
In order to remove, or shred files permanently from your system you have to use a program that is capable of rewriting the files with random series of binary data multiple times. This process is often called shredding. That way, the actual content of the file has been overwritten and the possibilities to recover such a shredded file are mostly theoretical.
2. Spybot
A build-in function of spybot will also shred the file forever from your hard drive. This is also a freeware.
p/s: Visit my posting regarding recover file, but if you shred it using above methods, there is no way to recover the file back.
