    Hi, all.

    I would like to get the list of filenames in a current directory sorted by the date of the modification (from the most recent to the odlest). The following code returns only the files in the directory:

    NSArray* dirCont = [fm directoryContentsAtPath: [fm currentDirectoryPath]];

    Is there a way to get the filenames in dirCont sorted by some file attribute (for example NSFileModificationDate) directly without sorting the content on hand?

    TNX, UruLama.

    I'd like to know this too? Here is a long way:

    Code:
    -(NSString*)findLatestFileInDir:(NSString*)dir{
	
	NSFileManager *fileManager = [NSFileManager defaultManager];
	NSArray* contents = [fileManager directoryContentsAtPath:dir];
	NSDictionary *currentFileAttributes;
	NSDate* currentFileDate;
	NSString* latestFile;
	NSDate* latestFileDate = [NSDate distantPast];
	for (NSString* fname in contents) {
		//check file is newer
		currentFileAttributes = [fileManager fileAttributesAtPath:[NSString stringWithFormat:@"%@/%@",dir,fname] traverseLink:YES];
		currentFileDate = [currentFileAttributes objectForKey:NSFileModificationDate];
		if([currentFileDate laterDate:latestFileDate] == currentFileDate){
			latestFileDate = currentFileDate;
			latestFile = fname;
		}
	}
	return latestFile;
}
