Archive file. An archive file is a file that is composed of one or more computer files along with metadata. Archive files are used to collect multiple data files together into a single file for easier portability and storage, or simply to compress files to use less storage space. Archive files often store directory structures, error detection and correction information, arbitrary comments, and sometimes use built-in encryption.
Sevin (tm) Insecticide. Sevin is the trade name for a widely used synthetic insecticide containing the active ingredient carbaryl. Carbaryl belongs to the chemical class called carbamates. As insecticides go Sevin is only moderately toxic to mammals and is still widely used in gardens and landscapes.
This is a statement from one of the vendors of Sevin (Carboryl). Do not spray food crops within 1 day of harvest, except tomatoes where there is no limit.. The same vendor also says Carboryl kills all insects. It is highly toxic to bees which you want in your garden.
