內容簡介
已過時：自 WP v5.5 起，此外掛功能已納入 WP 核心，因此不再需要此外掛。如果您正在運行 WP v5.5 或更高版本，可以停用並刪除 / 移除此外掛。此外掛在 WordPress 版本小於 v5.5 的情況下仍可正常運作。
WordPress 可讓您從 ZIP 檔案安裝新的外掛程式或主題，但不允許您從 ZIP 檔案升級它們。如果您嘗試從 ZIP 檔案升級，您將收到一條錯誤訊息，顯示 "目標已經存在"，升級將失敗。WordPress 不允許您從 ZIP 檔案進行升級。
從 ZIP 檔案升級主題和外掛程式外掛可讓您輕鬆升級，避免 "目標已經存在" 的錯誤訊息。
還有一個選項可以創建舊的外掛程式或主題的備份副本，以防新版本出現問題。

原文外掛簡介
DEPRECATED: As of WP v5.5 this plugins functionality is included in WP Core and this plugin is not required anymore. If you are running WP v5.5 or greater, you can de-activate and delete/remove this plugin. This plugin will still continue work fine with versions of WordPress less than v5.5.
WordPress will let you install a NEW plugin or theme from a zip file, but it does NOT allow you to upgrade them from a zip file. If you try to upgrade from a zip file, you will get an error message that says “destination already exists” and the upgrade will fail. WordPress will not allow you to upgrade from a zip file.
Update Theme and Plugins from Zip File will allow you to easily upgrade from a zip file, avoiding the “destination already exists” error message.
There is also an option to create a backup copy of the old plugin or theme, in case there is a problem with the new version.
