NetBeans internally uses the concept of a
virtual filesystem.
This interface is used by all upper layers of NetBeans to read &
write files, mount & display directories, move and delete files, and
allow external compilation and execution to find libraries correctly.
NetBeans itself implements two filesystems: a local filesystem,
which encapsulates access to the operating system's normal files; and
a JAR filesystem, which
allows users to mount Java Archive Files as if they were read-only
directories.
Using the Filesystems API,
third parties may add support for access to file-like objects stored
in some different manner - for example, in a database or proprietary
object storage system. More commonly, module authors should use this
API whenever they need access to files; then their module should work
automatically with any filesystem supported by NetBeans.
Other capabilities provided by the Filesystems API include locking
files during write operations; listening for changes in a file's
status, so that another part of NetBeans may reflect that change; and
providing support for including the filesystem in the runtime class
path of an external compiler or executor.
