Overwrite empty space, data and metadata to prevent it from being recoverable.

Overwrite is a free open source program that will overwrite anything left behind on a disk when you delete files from your computer. This presents the possibility of the data involved, the metadata, and the empty space replacing the deleted files, continuing to contain sensitive information. This is retrievable with recovery software. Even fragments remaining on a disk may possibly impact your privacy and security at a later date.

While software programs delete data that you no longer require, it is not immediately entirely deleted. Even later, it may still be recoverable - anything can be recovered until it is completely overwritten. You must take extra steps to erase sensitive data that is left behind. The Overwrite utility uses the operating system to overwrite the remaining data and metadata to fully prevent data recovery.

Overwrite ensures your security

When your operating system deletes a file, the space it fills becomes marked as free space - that is, free to be used by new files. However, both data and metadata being deleted is still present and can be recovered right up until the 'empty' space is actually overwritten by new data.

Overdrive selectively overwrites file names and content using -dirs and -data parameters to specify the metadata and the extent of the data to overwrite. Block size, the quantity of data, and the number of files can all be specified so that the program can safely erase sensitive data without any risk in overwriting other disk storage areas.

Using Overwrite to prevent metadata and data recovery

Downloaded, the open-source code can, depending upon the operating system, be compiled for the system or run using the Tiny C compiler. Overwriting options are provided within the source code - i.e. using random content or ones, defaulting to 0. You specify the block size used by your Windows system - 4096 for NFTS and EXT4 or 512 for USB drives. You can overwrite deleted files from the command line using, for example, overwrite -dirs:10 -data:10mb -path:c: or launch the Overwrite user interface.

Running the Overwrite user interface (overwrite-ui.exe), you are provided with Metadata and Data input bars for the number of files and amount of data. Next, there are drop-down Data units (MB, GB, or all) and Data content options and a Block size input bar. Any change to this depends on the Destination path selected next.

The interface displays your input and a progress bar and a panel beneath it reflects the progress of the operation including the time taken. There is a test parameter you can use before actually undertaking your overwrite to analyze the files and written directories.

Overwrite prevents data recovery by overwriting the empty spaces on a disk created by deleting files and their contents, erasing any sensitive data that could otherwise be retrieved by recovery software. It works on all Windows systems and requires Microsoft .NET Framework 2.0 or above.
