It’s part of the document-type declaration in your app’s Info.plist. I wouldn’t recommend NSFileWrapper for large files, because it reads all of a file into memory. The same goes for the usual file-I/O convenience methods on NSData, NSString. etc. — for some reason the Foundation APIs have always been biased toward reading/writing entire files. This is very convenient, but not scaleable. If your app’s performance is suffering because of large files, then use streams instead, and try to only read the part of the file that’s necessary. Or use a database like SQLite, which can easily handle terabyte-size files. (If you don’t want to deal with SQL queries, there are simpler key/value databases like LevelDB, LMDB, Kyoto Cabinet and Berkeley DB.) —Jens _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
