Indesign file recovery

If this happen do not do any recovery. Delete all lock and recovery files. Keep only the original. Rename the file. Open it and save as IDML and open the IDML, save as INDD.

If this does not work use the script blind open to save the file without opening it.

// blindOpen_and_IDML-Export.jsx 
 
var _file = File.openDialog("InDesign File"); // Select an INDD file 
if(_file != null) 
{ 
	var d = app.open(_file, false); // Open an INDD file without showing it 
	d.exportFile(ExportFormat.INDESIGN_MARKUP,  File(_file.fullName.replace(/.indd$/i,'.idml'))); // Export to IDML 
	d.close(SaveOptions.NO); // close without saving 
} 

If it's not able to recover the file then I am afraid we are in a bad state. Read the following article and see if you find something useful

On another note don't you have the file saved apart from the autosaved copy that is failing recovery. In that case atleast you will have the file till the last saved session. In such a case we can remove the recovery data manually and atleast start work again

You may need to recover it from a backup.
