Using quazip for extracting multiple files.

[akshaysulakhe]

Hello friends,
I am using QuaZip for extracting multiple files from a archive. I just need help on one small thing. As per the documentation of quazip says, amongst, JICompress, there is a method which can be used to extract multiple files at a given time. Link:- http://quazip.sourceforge.net/classJ...a28f837fab73ae

QStringList JlCompress::extractFiles(QString fileCompressed,QSringList files,QString dir=QString() )[static]
Parameters:
fileCompressed The name of the archive.
files The file list to extract.
dir The directory to put the files to, the current directory if left empty.
Returns:
The list of the full paths of the files extracted, empty on failure.

My apologies for the redundancy. As of now, i have the object and all of JICompress. I want to extract all files from the archive. I dont understand 2 parameters here. The return parameter, I dont understand why its necessary, as we are specifying the path of extraction. And what should i put for the 2nd parameter where is says the file list to extract. How can i say all, there are a lot of files, i cant just go on specifying names for each, as their names might change. Sorry for the long thread. Thank you for your time.

here a snippet from a library I wrote for my own purpose:

void extractAll( QuaZip& archive )
{
	// extracts all files from the archive and saves
	// them onto disk
	//
	// just a simple implementation for evaluation.
	// error handling has not been implemented yet!
 
	for( bool f = archive.goToFirstFile(); f; f = archive.goToNextFile() )
	{
		// set source file in archive
		QString filePath = archive.getCurrentFileName();
		QuaZipFile zFile( archive.getZipName(), filePath );
		// open the source file
		zFile.open( QIODevice::ReadOnly );
		// create a bytes array and write the file data into it
		QByteArray ba = zFile.readAll();
		// close the source file
		zFile.close();
		// set destination file
		QFile dstFile( filePath );
		// open the destination file
		dstFile.open( QIODevice::WriteOnly | QIODevice::Text );
		// write the data from the bytes array into the destination file
		dstFile.write( ba.data() );
		//close the destination file
		dstFile.close();
	}
}

void extractAll( QuaZip& archive )
{
	// extracts all files from the archive and saves
	// them onto disk
	//
	// just a simple implementation for evaluation.
	// error handling has not been implemented yet!

	for( bool f = archive.goToFirstFile(); f; f = archive.goToNextFile() )
	{
		// set source file in archive
		QString filePath = archive.getCurrentFileName();
		QuaZipFile zFile( archive.getZipName(), filePath );
		// open the source file
		zFile.open( QIODevice::ReadOnly );
		// create a bytes array and write the file data into it
		QByteArray ba = zFile.readAll();
		// close the source file
		zFile.close();
		// set destination file
		QFile dstFile( filePath );
		// open the destination file
		dstFile.open( QIODevice::WriteOnly | QIODevice::Text );
		// write the data from the bytes array into the destination file
		dstFile.write( ba.data() );
		//close the destination file
		dstFile.close();
	}
}

Thanks, i mainly wanted extractDir, which i got from elsewhere.
