+- The **File** widget can import any .xlsx, comma, or tab-delimited data file or URL. Use the **File** widget and, if needed, select class and meta attributes.
 - To specify the domain and the type of the attribute, attribute names can be preceded with a label followed by a hash. Use c for class and m for meta attribute, i to ignore a column, and C, D, S for continuous, discrete and string attribute types. Examples: C#mpg, mS#name, i#dummy.
 - Orange's native format is a tab-delimited text file with three header rows. The first row contains attribute names, the second the type (*continuous*, *discrete* or *string*), and the third the optional element (*class*, *meta* or *time*).
