The Program Library is a Hacking Node where compiled programs are stored. Upgrading a Program Library will increase the amount of disk space. A Program Library node that is being upgraded does not decrease the number of programs that can be stored.
The programs stored in this node are not considered resources. If this Node is captured via hacking, the stored programs will not be stolen. The contents of the Program Library can be accessed by pressing the virus button in the game interface. From there, installed programs can be erased to make room for new programs.
The maximum level a Program Library can be upgraded to is 21. The maximum number of Program Libraries you can have on your network is three. When deleting nodes, you will be unable to delete a Program Library unless you have two or more on your network already.
The icon of the node in the network represents the number of installed programs in it. As of Patch v.1.012, visuals of the Program Library display more accurately, and can now be filled to the top.
|Level 1||Levels 2-4||Levels 5-7|
|Levels 8-11||Levels 12-16||Levels 17-21|
- Building extra Program Libraries will significantly boost the number of programs you can store and is usually worth building as soon as possible.
- Each upgrade always increases disk space by 5, so it is best to upgrade the lowest level Libraries first.
