具體操作請參照以下步驟：
1、首先在網上下載好winRAR軟件的安裝包，直接安裝到電腦中即可。
/iknow-pic.cdn.bcebos.com/b812c8fcc3cec3fd79b9aa97d888d43f86942748"target="_blank"title=""class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/b812c8fcc3cec3fd79b9aa97d888d43f86942748?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="/b812c8fcc3cec3fd79b9aa97d888d43f86942748"/>
2、然後在電腦中找到要被壓縮的文件，用鼠標進行選中。
/iknow-pic.cdn.bcebos.com/203fb80e7bec54e70c2f17fcb7389b504ec26a14"target="_blank"title=""class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/203fb80e7bec54e70c2f17fcb7389b504ec26a14?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="/203fb80e7bec54e70c2f17fcb7389b504ec26a14"/>
3、然後點擊鼠標右鍵，在快捷菜單中點擊winRAR的快捷選項“添加到壓縮文件A”。如果需要快捷壓縮可直接點擊“添加到XXX”選項。
/iknow-pic.cdn.bcebos.com/5ab5c9ea15ce36d3c68d8ed234f33a87e850b142"target="_blank"title=""class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/5ab5c9ea15ce36d3c68d8ed234f33a87e850b142?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="/5ab5c9ea15ce36d3c68d8ed234f33a87e850b142"/>
4、進入壓縮參數設置界面後。可以按按個需要對各項參數進行設置，設置完點擊“確定”。
/iknow-pic.cdn.bcebos.com/b64543a98226cffca701b350b7014a90f603ea2d"target="_blank"title=""class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/b64543a98226cffca701b350b7014a90f603ea2d?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="/b64543a98226cffca701b350b7014a90f603ea2d"/>
5、然後等待文件壓縮完成。完成以上設置後，即可用WinRAR軟件壓縮文件。
