RFormat</title><shortdesc>This topic describes how to format a device.</shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>
<p>The <xref href="GUID-9D7E765B-6872-3EB9-9D5B-1503FA466EC1.dita"><apiname>RFormat</apiname></xref> class formats a device, one step at a time. </p>
<p>The object must first be opened on a device, and then each track is formatted
using <codeph>Next()</codeph>. The following code fragment shows how this
is done: </p>
<codeblock id="GUID-AAC0A2B2-4C5A-55F8-9DA4-820D42C27457" xml:space="preserve">...
_LIT(KDriveA,"A:");
...
RFs fs;
User::LeaveIfError(fs.Connect());
...
RFormat format;
TInt tracksRemaining;
User::LeaveIfError(format.Open(fs,KDriveA,EHighDensity,tracksRemaining));
while (tracksRemaining)
    {
    User::LeaveIfError(format.Next(tracksRemaining));
    }
format.Close();</codeblock>
