如何用QQ传送大于4G的文件？

只需要将文件夹压缩即可。
1、首先需要在桌面上右击文件夹，在其弹出的下拉菜单中找到并点击“添加到压缩文件”按钮：

/iknow-pic.cdn.bcebos.com/78310a55b319ebc4149a09828d26cffc1f1716ce"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/78310a55b319ebc4149a09828d26cffc1f1716ce?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/78310a55b319ebc4149a09828d26cffc1f1716ce"/>

2、接着需要在接下来弹出的页面框中改一下名称为rar格式后，点击“确定”按钮：

/iknow-pic.cdn.bcebos.com/5ab5c9ea15ce36d32a19fd2b35f33a87e950b188"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/5ab5c9ea15ce36d32a19fd2b35f33a87e950b188?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/5ab5c9ea15ce36d32a19fd2b35f33a87e950b188"/>

3、最后只需要发送给好友即可解决QQ怎么传输大于4G的文件问题：
