R: Get a list of available volumes

getVolumes {shinyFiles} | R Documentation

## Get a list of available volumes

### Description

This function is intended as an input to the roots parameter in `fileGetter()` and `shinyFileChoose()`. It returns a function that returns a named vector of available volumes on the system. This construction makes it dynamic so that a shinyFiles instance reflects new volumes as they get added (e.g. usb drives). The function takes a single argument giving names of volumes the developer wants removed from the return value.

### Usage

    getVolumes(exclude)

### Arguments

`exclude` | A vector of volume names to be excluded from the return value

### Details

The function is OS specific and looks for volumes/drives in different places depending on the system on which shiny is running.

Windows

  Returns all drives mapped to a letter

Mac OSX

  Looks in /Volumes/ and lists the directories therein

Linux

  Returns the system root

If the function does not recognize the system under which it is running it will throw an error

### Value

A function returning a named vector of available volumes
