 Description

 File widget reads the input data file (data table with data instances)
 and sends the data set to its output channel. It maintains
-a history of most recently opened files. For convenience, the history also includes
-a directory with the sample data sets that come pre-installed with Orange.

 The widget reads data from simple tab-delimited or comma-separated files,
 as well as files in

-Tab-delimited data file can include user defined symbols for undefined values. The symbols for
-"don't care" and "don't know" values can be specified in the corresponding edit lines. 
-The default values for "don't know" and "don't care" depend upon format. Most users will 
-use tab-delimited files: keep the field empty or put a question mark in there and that's 
-it. Most algorithms do not differ between don't know and don't care values, so consider 
-them both to mean undefined.

-Orange will usually treat the attributes with the same name
-but appearing in different files as the same attribute, so a classifier which uses the 
-attribute "petal length" from the first will use the attribute of the same name from 
-the second. In cases when attributes from different files just accidentally bear different 
-names, one can instruct Orange to either always construct new attribute or construct them when 
-they differ in their domains. Use the options on dealing with new attributes
-with great care (if at all).

 Example

-Most Orange workflows would probably start with the File widget. In the schema below,
-the widget is used to read the data that is sent to both :ref:`Data Table` widget and
-to widget that displays :ref:`Attribute Statistics`.

    :alt: Example schema with File widget
Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
