## directory

directory — Reads a directory and outputs to a string array a list of file names.

## Description

Reads a directory for files and passes them to a string array. Users can set the file type by passing a file extension as a string.

## Syntax

    SFiles[] directory SDirectory[, SExtention]

## Initialization

SDirectory -- a string that identifies the directory to browse for files

SExtention -- Optional. Sets the desired file type. If left out, all files names will be retrieved.

## Performance

SFiles[] -- a string array that holds the names of all files of a given type found in the directory.

| Note
This works at i-time only and will not pick up changes made to the directory after performance has started.

## Example

This example shows how directory can be used to browse for .wav files in a fixed location. printf_i is then used to print the file names. It uses the file directory.csd.

Example 231. Example of the directory opcode.

    until iCnt>=iNumberOfFiles do
    	printf_i "Filename = %s \n", 1, SFilenames[iCnt]
    	iCnt = iCnt+1
