+If this box is checked, EmEditor uses file-based operations for editing, and reduces the system's memory usage. If the Read Unmodified Lines from the Original File check box is also set, unmodified lines will be read from the original file, which increases the speed to open a file. If not, the file contents will be saved as a temporary file while opening a file, which reduces the file opening speed. Both cases reduce the system's memory usage.

+## Minimum File Size to Enable Disk-Based text box
 
-If this box is checked, EmEditor automatically determines whether a temporary file should be used to open a file depending on the available memory size. When this option is enabled, EmEditor will use a temporary file if the file size to be opened is more than approximately 1/4 of the available memory. Setting this option allows EmEditor to optimize the speed both for read and write. However, if you mainly read large files and don't edit them, disabling this option and entering a smaller number in the **Minimum File Size to use Temporary File** text box makes EmEditor to read large files faster.
