I'm curious to know how to completely erase all possible traces of files in Windows 7.
For example, let's say I have a subfolder containing five different files at work deemed sensitive (A document, a video file, a RAR, an image, and text file).
What are the steps I have to take if I want to completely erase all traces of these files without reformatting or doing something similar?
I can think of only a few things:
- Erase Temp files stored by WinRAR
- Delete the thumbnail icon database stored in AppData (.DS file)
- Disable Data storage by the Windows 'hibernate' feature
Am I correct in assuming that simply "shredding" a folder won't completely erase all traces of the files in said subfolder?
Is it safe to assume that using software such as CCleaner would sufficiently remove all traces of said subfolder (if using the 'secure delete' option)?
How can I reach a state of confidence where I can remove all traces of these files, and bring my work laptop home knowing that the files and all traces of those files are completely wiped out? (Or can I ever be completely confident?)
