Today I accidentally logged into iAsk and found a very practical free service provided by iAsk - [Resource Sharing]. This service allows registered users of iAsk or Sina to upload files not exceeding 30M each to share with netizens. It supports many file types, and users can freely set the required iAsk points for downloading the file. If set to 0 (i.e., no points are needed to download), other netizens do not need to register or log in, and they can directly download the file you uploaded. In this way, the [Resource Sharing] service is equivalent to an unlimited-space free online disk. After testing the upload speed, it is pretty good. Additionally, if you want to upload larger video files, you can use the [Sina Blogcast] service, which allows registered users of iAsk or Sina to upload files not exceeding 100M each to share with netizens. It supports many video formats and the speed is also quite good. I recommend everyone try out the free storage service provided by Sina.
