Why can't oppo mobile phone find the installation package?

In order to make room for the mobile phone, the installation package downloaded from the "software store" APP or "game center" APP that comes with the mobile phone is placed in the temporary storage area. After the software installation is completed, the installation package will be automatically deleted. The software itself is updated, and the installation package downloaded through the browser can be viewed in "file management App > compressed package" ~ If you need to delete the installation package, just press and hold to delete the installation package. This answer applies to all OPPO models.
