    <p>I've written methods that help me get the size of files/folders and translate the result in a human readable string. Problem is, when this size exceeds about 2.1GB, the number returned changes to a random negative number, like "-4324234423 bytes", which is useless.</p> <p>Things I've found out about &amp; done about this issue:</p> <ul> <li>32GB is limited to this size, so I compile in 64bit instead.</li> <li>I've tried using both CGFloat and NSUInteger, but both still return the same value as NSInteger.</li> </ul> <p>I am quite frustrated, I don't know what I am missing. Here are my methods:</p> <pre><code>- (NSString *)stringFromFileSize:(int)theSize { CGFloat floatSize = theSize; if (theSize&lt;1023) return([NSString stringWithFormat:@"%i bytes",theSize]); floatSize = floatSize / 1024; if (floatSize&lt;1023) return([NSString stringWithFormat:@"%1.1f KB",floatSize]); floatSize = floatSize / 1024; if (floatSize&lt;1023) return([NSString stringWithFormat:@"%1.2f MB",floatSize]); floatSize = floatSize / 1024; return([NSString stringWithFormat:@"%1.2f GB",floatSize]); } - (NSUInteger)sizeOfFile:(NSString *)path { NSDictionary *fattrib = [[NSFileManager defaultManager] attributesOfItemAtPath:path error:nil]; NSUInteger fileSize = (NSUInteger)[fattrib fileSize]; return fileSize; } - (NSUInteger)sizeOfFolder:(NSString*)folderPath { NSArray *contents; NSEnumerator *enumerator; NSString *path; contents = [[NSFileManager defaultManager] subpathsAtPath:folderPath]; enumerator = [contents objectEnumerator]; NSUInteger fileSizeInt = 0; while (path = [enumerator nextObject]) { NSDictionary *fattrib = [[NSFileManager defaultManager] attributesOfItemAtPath:[folderPath stringByAppendingPathComponent:path] error:nil]; fileSizeInt +=[fattrib fileSize]; } return fileSizeInt; } </code></pre> <p>What am I missing? Is NSFileManager returning a 32bit value? What's causing this?</p> <p>Thanks!</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
