You can only view files in that your App's sandbox. Every App has got a Documents, Cache and temp folders.

sample code :

NSError *err        = nil;
NSArray *myPathList = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES);
NSString *myPath    = [myPathList  objectAtIndex:0];
NSArray *dirContent = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:myPath error:&err];
if(err) NSLog(@"ERROR: %@",[err localizedDescription]);
NSMutableArray *filePaths  = nil;

int count = (int)[dirContent count];
for(int i=0; i<count; i++)
{
    [filePaths addObject:[dirContent objectAtIndex:i]];
}
return filePaths;
