Questions tagged [local]

A tag for questions about accessing resources local to a given runtime environment or network.

Accessing data on a local network, or accessing files local to the computer can pose unexpected complications, especially when using languages that are not typically used for local resource access.

Additional exceptions, or hardware/firmware considerations, can come into play in these scenarios that are often abstracted away when accessing remote resources.
