The overwrite function in BleachBit is designed to securely delete files so that they cannot be recovered later. Here’s how it works:
How Overwrite Works
- Single Pass of Blank Data: When you enable the overwrite option, BleachBit wipes the data with a single pass of blank data. This means it writes over the existing data with zeros or other patterns to ensure it is no longer readable.
- Wiping Slack Space: At the end of a file, BleachBit may write additional data to wipe the slack space. Slack space is the unused space in a file cluster that can still contain remnants of old data.
- Renaming Files: To further obscure the original data, BleachBit renames the file to a long, random name and then to a short name before finally deleting it.
Benefits of Overwriting
- Prevents Data Recovery: By overwriting the data, BleachBit makes it extremely difficult for data recovery tools to retrieve the original contents of the file.
- Enhances Privacy: This function is particularly useful for ensuring that sensitive information is completely removed from your system.
RMMmax will send an overwrite command to overwrite current options list.
