1、首先在桌面上將演示文稿點擊打開。
/iknow-pic.cdn.bcebos.com/2e2eb9389b504fc22982fe5eebdde71191ef6d88"target="_blank"title=""class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/2e2eb9389b504fc22982fe5eebdde71191ef6d88?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="/2e2eb9389b504fc22982fe5eebdde71191ef6d88"/>
2、打開了之後，在文稿上面點擊文件這個選項。
/iknow-pic.cdn.bcebos.com/32fa828ba61ea8d3d5583d5f990a304e251f5876"target="_blank"title=""class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/32fa828ba61ea8d3d5583d5f990a304e251f5876?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="/32fa828ba61ea8d3d5583d5f990a304e251f5876"/>
3、點擊了之後，在彈出的窗口裏面選擇另存為。
/iknow-pic.cdn.bcebos.com/faf2b2119313b07e16bc195302d7912397dd8c6c"target="_blank"title=""class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/faf2b2119313b07e16bc195302d7912397dd8c6c?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="/faf2b2119313b07e16bc195302d7912397dd8c6c"/>
4、然後在保存的時候將文件類型選擇為PPSX格式。
/iknow-pic.cdn.bcebos.com/5fdf8db1cb1349541f8ea13f584e9258d0094adc"target="_blank"title=""class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/5fdf8db1cb1349541f8ea13f584e9258d0094adc?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="/5fdf8db1cb1349541f8ea13f584e9258d0094adc"/>
5、保存完畢之後，如需要將這種格式的文件打開，則需要在office2007以上的版本打開，低於office2007的版本是無法打開此文件的。
