Description Usage Arguments Details Value See Also Examples
These function sets up the required connection to the client in order for the
user to navigate the filesystem. For this to work a matching button should be
present in the html, either by using one of the button generating functions
or adding it manually. See shinyFiles-buttons
for more details.

The input object of the |

The same ID as used in the matching call to

The time in milliseconds between file system lookups. This determines the responsiveness to changes in the filesystem (e.g. addition of files or drives) |
session |
The session object of the shinyServer call (usually

The default root to use. For instance if

Arguments to be passed on to |
Restrictions on the access rights of the client can be given in several ways.
The root parameter specifies the starting position for the filesystem as
presented to the client. This means that the client can only navigate in
subdirectories of the root. Paths passed of to the restrictions
parameter will not show up in the client view, and it is impossible to
navigate into these subdirectories. The filetypes
parameter takes a
vector of file extensions to filter the output on, so that the client is
only presented with these filetypes. Whenever a file or folder
choice is made the resulting files/folder will be accessible in the input
variable with the id given in the parameters. This value should probable be
run through a call to one of the parser (shinyDropFiles-parsers
) in
order to get well formatted paths to work with.
A reactive observer that takes care of the server side logic of the filesystem connection.
