Thank you for the post.
I am unable to replicate. To attempt to replicate, I performed the following steps:
1. Uploaded a database called "External Storage" with a single container field (externally stored) to FileMaker Server 13.0v3.
2. Using the Admin Console, closed the file.
3. Downloaded the database.
Note: At this point, I have a folder titled "External Storage" (name of the database) and within the folder is the database and another folder titled "External Storage" (including the container data).
4. File > Recovery > External Storage.fmp12 > Select > Save
Note: At this point, I have an additional database file titled "External Storage Recovered"
5. Opened "External Storage Recovered.fmp12" and confirmed the container data exists.
"Run the option to recover with the preserve external container option selected."
Where is this recovery option located?
No files were deleted during my testing. Perhaps, I am missing a step to replicate?
