Lizard Protector Viewer, for security reasons, handles file decryption operations in memory only. No temporary or cache files are created. Depending on machine memory size, processor speed, and operating system this restricts the maximum size of file that can be processed.
We advise that you should not protect files greater than 200MB in size for reliable use across a wide range of Windows clients.
The largest file size supported for flash files is 12MB in size.
Please bear in mind that protected content viewed over a web site will be much slower than the user viewing it locally on their computer (since content must be downloaded first before it can be decrypted in memory). You may therefore want to distribute large files on CD.
