Saving new files does not automatically destroy every previously deleted file.
The operating system and file system determine where new information is written. Some new files may occupy previously unused space, while others may reuse locations that once contained deleted files.
As a result:
- Some deleted files may remain intact.
- Some files may be partially overwritten.
- Other files may be completely overwritten.
- Unaffected files in other areas of the drive may remain recoverable.
The amount of new data saved is not, by itself, sufficient to determine exactly which deleted files have been destroyed.
The type of file system, the original file locations, and subsequent write activity all matter.
If important information has disappeared, stop using the affected drive and consult a qualified specialist. Additional writes can reduce the amount of recoverable data.
