FAQ: What is the maximum file size for Safeguard documents?

Lizard Safeguard 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 and Macintosh clients.
