As with HTML documents, you can choose to use a filter with or without the element ($[officename] Impress) in the name to open a $[officename] graphics file. If without, the file will be opened as a $[officename] Draw document. Otherwise, the file saved by an old program version is now opened in $[officename] Impress.
与 HTML 文档相类似，您可以选择使用名称中包括或不包括元素 ($[officename] Impress) 的过滤器打开 $[officename] 图形文件。如果不包括，则文档将作为 $[officename] Draw 文档打开；否则，以旧版本的程序保存的文件将在 $[officename] Impress 中被打开，这样，您就可以把这个文档用作演示文稿的基础。
