How to set an absolute path in an OSGi .config file for a directory on a shared network drive

Issue

We are attempting to use a Document Library directory "External_Library" on a shared network drive, but cannot determine how to use an absolute path instead of a relative path; during startup, a relative path is being used and the full directory structure is getting created within Liferay Home.
Our Liferay bundle is hosted in a Windows environment (with the network drive on a server using Ubuntu), and we'd like to use the Advanced File System Store.

When setting an absolute path for a directory, per the Universal Naming Convention, it is necessary to use a double slash at the beginning of the path to specify a path on a separate host/server.
As such, the process to use an OSGi .config file for the Advanced File System Store configuration (with the appropriate syntax for an absolute path on a shared drive) would be to create a file titled com.liferay.portal.store.file.system.configuration.AdvancedFileSystemStoreConfiguration.config,
placed within [Liferay_Home]\osgi\configs, with the following content included:

rootDir="//server-name/directory/path/External_Library"

Depending on the operating systems in use, there may be slight syntax modifications that need to be made to the slashes included in the path. For example, if using backslashes in a Windows path instead of forward slashes, any double backslash is interpreted by the OS as a single backslash (so a path of \\server-name would be interpreted as just \server-name -- pointing to a folder called "server-name" at the root directory of the current host, instead of the external server/host).
With this in mind, in a Windows environment the following configuration would be valid syntax for the example above:
```
rootDir="\\\\server-name\\directory\\path\\External_Library" 
```
