The tmp file extension is generally used for temporary files. Temporary files are usually generated by various software for two reasons: a backup file or a cache.

In the case of cache files these can be generated automatically by programs that run out of memory space to allocate for tasks.

Temporary files should be deleted by the program that generated them.

However sometimes (due to a software crash or poor software design) the tmp files aren't removed and potentially can take up a substantial amount of room on your hard-drive. In most cases it's safe to delete them.
