Hi Wendy F
If simply opening a CD causes files to disappear, that is not normal behavior. CDs that are finalized (CD-ROM, audio CDs, most software discs) are generally read-only, so viewing them should not delete files.
A few things to check:
- Are the files actually deleted or just hidden?
- Open File Explorer.
- Select View > Show > Hidden items.
- Check whether the files reappear.
- Try the CD on another computer
- If the files are visible there, the issue may be related to Windows, a CD-writing application, or the optical drive on the first PC.
- Protect important files
- Copy the files from the CD to your computer or another storage device as soon as possible.
- If the disc is a CD-RW and you want it preserved, avoid using software that can write to the disc.
