You can "develop text" that appears as a description whenever someone opens the archive:
: Version 7.00 of the software specifically filters out "control character 27" from console output for security.
: A FedRAMP Readiness Assessment Report (RAR) often uses tables (e.g., Table 4.15 on page 27) to document security controls.
: Alternatively, use the -z switch to import text from an existing file: rar c -zcomment.txt 27.rar . 3. Generate a File List for Backup
