QFile file（path）；
file.exists();
2、复制文件
bool copy(const QString &fileName, const QString &newName);
3、建立快捷方式

4、开机启动程序
void MainWindow::autoStart(IniFile &inifile,const QString &appPath)
QString appN
appName = appPath.right(appPath.length()-appPath.lastIndexOf("/")-<span style="color: #);
inifile.readIni("AUTOSTART",flag);
if(flag == "true")
QSettings *reg = new QSettings("HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows/CurrentVersion/Run",
QSettings::NativeFormat);
reg-&setValue(appName,appPath);
5、运行程序
&&&&&QProcess *process = new QP&&&&& //这个不加析构，不退出&&&&&process-&start(appPath);
6、删除目录及其下所有文件
void deleteDir(const QString &d)
QDir dir(d);
foreach (QFileInfo inf, dir.entryInfoList(QDir::Dirs|QDir::Files)) {
if(inf.isFile())
dir.remove(inf.absoluteFilePath());
else if(inf.isDir() &&
inf.fileName() != "." &&
inf.fileName() != "..")
deleteDir(inf.absolutePath()+"/"+inf.fileName());
dir.rmdir(dir.absolutePath());

Self Extractor (SFX) File Format
---------------------------------
Starting from the end of the archive and working backwards :-
Header Info
Signature - Identifier for SFX archive
Number of files in archive
Table of Contents
Contains one record in the following format for each file
Length of filename
Length of File
Offset in archive to data
Data Segment
Each file is written (uncompressed) here in the order of the TOC
After this is the extractor executable.
