: how would you check if a file is valid ?
A few possible ways come to mind -
1. Have a header record that includes some kind of checksum or validation sequence.
2. File size should be divisible by record size.
3. When reading in the file, if you get a pointer that points outside of the file, you probably have problems.
4. Every time you output a file, write its name to the registry. Create a Windows shell extension that hooks into any copy or move and updates the registry as needed to track any files you create.
