I forgot the code:
NSURL* directoryURL = [NSURL
URLWithString:@"/.DocumentRevisions-V100/"];
NSFileManager* manager = [NSFileManager defaultManager];
NSArray* keys = @[NSURLNameKey, NSURLIsDirectoryKey];
NSDirectoryEnumerator* enumerator = [manager
enumeratorAtURL:directoryURL includingPropertiesForKeys:keys
options:NSDirectoryEnumerationSkipsSubdirectoryDescendants
errorHandler:^BOOL(NSURL *url, NSError *error){return true; }];
for (NSURL* file in enumerator)
{
}
