I wonder if your memory issues are related to autorelease issues when using [NSDirectoryEnumerator nextObject:]
If you are using enumeratorAtPath, I suggest doing you loop like this (from http://www.cocoadev.com/index.pl?NSDirectoryEnumerator): NSDirectoryEnumerator *enumerator = [[NSFileManager defaultManager] enumeratorAtPath: path]; NSAutoreleasePool *innerPool = [[NSAutoreleasePool alloc] init]; while ((curObject = [enumerator nextObject])) { // do stuff [innerPool release]; innerPool = [[NSAutoreleasePool alloc] init]; } [innerPool release]; innerPool = nil; (Basically you need to ensure that the [enumerator nextObject] result doesn't end up in a higher-level autorelease pool as they will live for the duration of the entire scan Matt On 23 Feb 2011, at 06:08, Laurent Daudelin wrote: > I need to write an application that will scan entire drives and compare files > between the 2 drives.
