NSFilemanager and secure removal

Is there an officially supported way to safely delete files on Mac OS X 10.5 +?

If not, about which I can move all the files (using NSFilemanager) to a shared folder and use srm: from the shell script. Will it delete all the file traces or will the file still be restored due to the move operation?

in advance for any help / suggestions.

AFAIK, move is not going to copy bytes, just change the pointers in the file system.

:

NSError *err;
NSFileManager *fileManager = [[NSFileManager alloc] init];
[fileManager removeItemAtPath:path error:&err];

- NSString, , .
