Answer 1

If you have a path like jinx said, you could do this

NSNumber *theFileSize = [NSNumber numberWithInt:0];
NSFileManager * filemanager = [NSFileManager defaultManager];

if([filemanager fileExistsAtPath:fullFilePath])
{
    NSDictionary * attributes = [filemanager attributesOfItemAtPath:fullFilePath error:nil];
    theFileSize = [attributes objectForKey:NSFileSize];
}

[self convertbyteToKB_MB:[theFileSize  intValue];

...

-(NSString*)convertbyteToKB_MB:(int)byte 
{
NSString    *retSize = [NSString stringWithFormat:@"%d bytes",byte];
float       fByte = byte;
if (byte > 1024)
{
    //Kilobytes
    fByte = fByte / 1024;
    retSize = [NSString stringWithFormat:@"%.1f KB",fByte];
}

if (fByte > 1024)
{
    //Megabytes
    fByte = fByte / 1024;
    retSize = [NSString stringWithFormat:@"%.1f MB",fByte]; 
}

return retSize;
}
