How to delete a file without leaving traces ?





When you delete a file, even without going through the recycle bin, the file is not completely deleted from the hard drive.
In reality, only the indexing information located in the allocation table and which provides access to the sectors of the disk where the file is written are deleted. The data in the file is still on disk.
Disk space is regained although data is still present on the disk because the file system considers the file deleted as soon as the index no longer exists. As long as the space used by this file has not been used by another file, all data is recoverable. There are many utilities available to restore an erased file by directly reading disk sectors. WinSesame (Pro version) has a function for deleting these residual traces because, following an encryption, it is important to thoroughly clean the hard disk of all traces of old files in clear.


Using WinSesame:


It is possible to use WinSesame to delete a file or even an entire folder without leaving any trace on the hard drive:


In the WinSesame options make sure that the Disk cleanup check box is checked and the number of passes at least equal to 2. These are the default values ​​of the program.


As soon as the program is installed, it can be used without any 
configuration to lock your documents, but it is likely that you want to 
configure the program to adapt it more precisely to your needs and take 
advantage of its flexibility of use.


To perform a secure erase of an entire file or folder, right click on it and choose WinSesame Protection. Provide any password you don't have to remember and confirm it. The file will be encrypted by WinSesame. The sectors formerly used by this file will be perfectly cleaned by WinSesame. Then you just have to delete the encrypted file without taking any special precautions because all the data that it would then be possible to recover on the disk sectors or in the recycle bin is encrypted and absolutely unusable.
