Differences between help formats

Internet connection

GN4.CHM file has to exist to your local drive. It is recommended not to access the file from a network drive, as Windows security setting may prevent you to display it. You don't need any Internet or network connection to read a CHM file.

Access time

The access time to table of contents, index and full-text search is very short - the access is instantaneous.

Up-to-date status

As file is stored on your computer, your copy may be out-of-date, i.e. your documentation may contain outdated information. See Getting updated documentation, or use the documentation on the Web site that is always 100% up-to-date.

Printing help

CHM format is typically not suitable to be printed, except for one topic at a time. Use PDF format if you want to print all text, or selected chapters.

Internet connection
