ADS invokes CommandLineInterpreter.getConnectionsDirectory() to get connection directory.

The implementation of CommandLineInterpreter.getConnectionsDirectory() is as follows:
(1) get current value of the CONNECTIONS shell variable.
(2) pass the value retrieved from (1) to ShellTools.dequote(value) to remove undesired contents where ShellTools.dequote(value) actually calls FilePathParser(value).parse() to perform its job.

The root cause of the problem described in this issue is FilePathParser().parse() takes "\\server\path\name" as input but returns it as "\server\path\name", i.e. the very first backslash is removed.

FilePathParser().parse() is only referenced by ShellTools.dequote(String), but ShellTools.dequote(String) is referenced in several places.

It seems that modifying FilePathParser().parse() will be difficult.

Perhaps we can work around this problem by just modifying CommandLineInterpreter.getConnectionsDirectory() and I will work on this tomorrow.

I agree.  In .getConnectionsDirectory(), instead of calling .dequote(), we can just put it inline and say, :

if ( !name.startsWith("\\\\") && (AQStringUtils.containsAny("'\"\\", name)) {
            name = new FilePathParser(name).parse();
}

Or something like that.
