Qt拷贝文件、文件夹（QFile::copy）

//拷贝文件：bool MyTest007::copyFileToPath(QString sourceDir ,QString toDir, bool coverFileIfExist){toDir.replace("\\","/");if (sourceDir == toDir){return true;}if (!QFile::exists(sourceDir)){return false;}QDir *createfile     = new QDir;bool exist = createfile->exists(toDir);if (exist){if(coverFileIfExist){createfile->remove(toDir);}}//end ifif(!QFile::copy(sourceDir, toDir)){return false;}return true;}//拷贝文件夹：bool MyTest007::copyDirectoryFiles(const QString &fromDir, const QString &toDir, bool coverFileIfExist){QDir sourceDir(fromDir);QDir targetDir(toDir);if(!targetDir.exists()){    /**< 如果目标目录不存在，则进行创建 */if(!targetDir.mkdir(targetDir.absolutePath()))return false;}QFileInfoList fileInfoList = sourceDir.entryInfoList();foreach(QFileInfo fileInfo, fileInfoList){if(fileInfo.fileName() == "." || fileInfo.fileName() == "..")continue;if(fileInfo.isDir()){    /**< 当为目录时，递归的进行copy */if(!copyDirectoryFiles(fileInfo.filePath(), targetDir.filePath(fileInfo.fileName()),coverFileIfExist))return false;}else{            /**< 当允许覆盖操作时，将旧文件进行删除操作 */if(coverFileIfExist && targetDir.exists(fileInfo.fileName())){targetDir.remove(fileInfo.fileName()); }/// 进行文件copyif(!QFile::copy(fileInfo.filePath(), targetDir.filePath(fileInfo.fileName()))){return false;}}}return true;}
