The default temporary directory is C:/TEMP with the ACE on NT4.0. The ACE is used to realize the semantics like the S_ISVTX bit on UNIX. So we should be able to freely operate files created by ourselves in the directory. But we can't delete them created by the new DLL. I propose ntsec adds the DELETE permission of the owner to files created in such directories. ____ | AIST Kazuhiro Fujieda <fujieda AT jaist DOT ac DOT jp> | HOKURIKU Center for Information Science o_/ 1990 Japan Advanced Institute of Science and Technology
