In demo mode, files containing up to 64 kilobytes of data can be saved.
Saving a file in demo mode is a safe, read-only operation and does not affect future recoverability.
(However other unrelated events happening on the computer may reduce your chances of a successful recovery.)
You can also preview a picture file (such as a file with the extension JPEG, BMP, TIF, PNG, etc.) of any size
by selecting the file name from the list and click on the "Preview" button on the Tool bar.
