I cannot find a variable named “%_SB_PRESERVE_BACKUPFILEEXT” in the list of possible system defined variables in the “Variable Name” dropdown list when I insert the “Set Variable…” statement into a SB script under versions 10.0.6976 or 11.0.7684.
1) Is there really an option to use the original file extension when SB is making an automatic backup, instead of auto incrementing a 3-digit file extension for the destination file?
2) If there really is an option to use the original file extension when creating an automatic backup (as determined by the “Project Properties / Advanced Settings / “Backup Replaced Files” option) does this mean it will replace an existing backup file if it exists or skip making the backup copy?
