Can not save data in subdirectory of Documents iPhone?

Your dataPath doesn't include tileImageName You should define a tileImagePath to include the tileImageName It should probably be NSString * tileImageName = NSString stringWithFormat:@"%@%@",currentDate,@". Png"; NSString * dataPath = documentsDirectory stringByAppendingPathComponent:@"MyFolder"; NSString * tileImagePath = dataPath stringByAppendingPathComponent:tileImageName; if (!NSFileManager defaultManager fileExistsAtPath:dataPath){ NSFileManager defaultManager createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:nil; } NSData * data = UIImagePNGRepresentation(tileImage); data writeToFile:tileImagePath atomically:YES So your dataPath is something like Documents/MyFolder and not Documents/MyFolder/20110622_011700. Png as you intended.

Thanks for quick reply. I will do it. How can I delete the folder so that all the data is deleted from folder?

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
