Thanks.
Can it work on iOS? It looks that it works in Windows.

I added this method in CCFileUtils to remove a folder and its’ files on iOS:

bool CCFileUtils::removeDirAndFiles(const char pDirectoryName)
{
NSArraypaths = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES);
NSString documentsDirectory = ;
NSStringdelPath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithUTF8String:pDirectoryName]];

if ([[NSFileManager defaultManager] fileExistsAtPath:delPath])
{
NSFileManager *fileManager = [NSFileManager defaultManager];
[fileManager removeItemAtPath:delPath error:nil];

return true;
}

return false;

}

I added this method in CCFileUtils to know if a dir or file is exist on iOS:

bool CCFileUtils::isFileExist(const char pName)
{
NSArraypaths = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES);
NSString documentsDirectory = ;
NSStringnewPath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithUTF8String:pName]];

if ([[NSFileManager defaultManager] fileExistsAtPath:newPath])
{
return true;
}
else
return false;
}
