Setting advanced file recovery options
FileMaker Pro uses certain default settings when it recovers a file. You can change these settings when you attempt to recover a damaged file.
Note  (FileMaker Pro Advanced) Runtime applications do not support advanced file recovery features.
To set advanced file recovery options:
Choose File menu > Recover.
FileMaker Pro displays the Advanced Recovery Options dialog box, with either the default recovery options selected (if this is the first time the dialog box is displayed during the current application launch) or with the most recent settings made during the current application launch.
Select one option for how you want FileMaker Pro to generate the new file.
Copy all the original data without checking the blocks and rebuild the tree structure in the recovered file.
Scan blocks and rebuild file (drop invalid blocks)
After the new file is generated, it is scanned and then a new database is rebuilt according to the options you select in the next step.
Rebuild the file’s schema. This option forces all records and field data to be scanned.
Note  Scanning all the records and field data may take a long time, but it’s the only option that recreates missing field or table definitions. If any fields or records are at invalid locations in the file, only this option will find and remove them.
Rebuild field indexes, and then select Now or Later
Remove the most recently used settings including page format, print settings, layout formatting defaults; and for every table in a file, the import and export order, recent sorts, recent finds, the last found set, and send mail options. (However, any saved finds are recovered.)
Bypass any scripts or layouts that are normally used when the file is opened. (Any “When opening this file” scripts created in File Options are disabled and FileMaker Pro creates a blank layout into which the file opens.) This option prompts you near the end of the recovery process to enter an account and password with full access to the database.
To use these settings the next time you recover a file during the same application launch, keep Use advanced options selected in the “Name new recovered file” dialog box. To change these settings, keep Use advanced options selected in the “Name new recovered file” dialog box, and click Specify.
To revert to the FileMaker Pro default recovery settings, deselect Use advanced options.
When Bypass startup script and layout is selected, the bypass will not be allowed if any one of these conditions exist:
If you change file recovery settings and then switch to using a script that bypasses dialog boxes, FileMaker Pro uses its default file recovery options (instead of those you set). If you return to recovering files using dialog boxes, however, the changed settings are restored.
Whenever you only want to bypass the layout to open the file, select Copy blocks as-is and Bypass on open script, and leave other options deselected.)
