I received error 001730 when trying to extract a .geodatabase file copied from an Android tablet. I tried copying the data to my C drive and also shortening file name, but still received the error.
The data is super important so anyway that the data can be extracted would be extremely helpful!
It's not an ideal solution but it has worked for me when I had this issue.
The runtime geodatabase is in a SQLite format. You can use a SQLite browser such as DB Browser for SQLite (which is free) to view the tables and extract the data including the coordinates. You can then recreate the data. Again, not ideal but it has worked for me before
