When GRAMPS opens a tree, it locks the tree, preventing you or anyone else opening it at the same time. In the event A second copy of starting a second GRAMPS instance, you will be able to open another family tree, but the tree already open will appear with the lock icon, indicating you cannot open it. Openening twice Closing the same database can and tree in the first copy of GRAMPS will lead make it available to errors be opened in your datathe second copy.

If you could open the same Family Tree in two GRAMPS at once, it is likely your data would be damaged. In the unlikely event of a crach crash of GRAMPS, the family tree will be left in a locked state. To unlock the tree, select the locked family tree, and click the {{man button|Unlock}} button that will be available. Only do this if you are sure no other instance copy of GRAMPS is open on using this family tree
