MW (Maple Worksheet) is the native format for Maple documents and worksheets.

It is an XML-based format and was introduced with Maple 9, replacing the Maple Classic Worksheet (MWS) format.

Maple has built-in facilities for exporting worksheets to other formats.

The DocumentTools package has several utilities for interacting with MW files.

$\mathrm{MWFile}≔\mathrm{FileTools}:-\mathrm{JoinPath}\left(\left[''example/BesselsEquation.mw''\right]\,\mathrm{base}=\mathrm{datadir}\right)$

$''C:\backslash Program\; Files\backslash Maple\; 2016\backslash data\backslash example\backslash BesselsEquation.mw''$

$\mathrm{DocumentTools}:-\mathrm{Retrieve}\left(\mathrm{MWFile}\,''L6''\right)$

$x^2\left(\frac{{\ⅆ}^2}{\ⅆx^2}y\left(x\right)\right)+x\left(\frac{\ⅆ}{\ⅆx}y\left(x\right)\right)+\left(-{\mathrm{\nu }}^2+x^2\right)y\left(x\right)=0$
