What Do Overwritten Files Mean 

When some crimes happen, the surveillance videos will be the key to investigations and evidence. When a video is overwritten, what does this mean? Overwrite means to record or copy new data over existing data when a file or directory is updated. When data is overwritten, new information is recorded over the old information. The unused file system clusters are used to record new information. This happens when the user continues to use the disk for various purposes and writes new files over the old ones.
