ma sve se to moze vratit...

Quote:
An operating system, such as MS-DOS and Windows, uses a file system to keep track of the data on the hard disk: directories, files, their location, size, dates etc. Using a file system is noticeably faster than parsing the information directly from the disk, but also causes problems when the user wants to securely remove a file.

Normally, when you delete a file, the operating system does not actually erase the file; it only removes the reference of the file from the file system table and marks the area occupied by the file unused. Therefore anyone can recover the file using any disk maintenance utility capable of reading the disk directly. The data will not be destroyed until a program writes over the deleted file, and even after that it may be possible to recover some or all of the data by studying the disk with specialized equipment.
ako ne koristis nekii specijalan program za brisanje, nije problem nista vratit.
