The first two days to see the F disk is about to explode, think of it to clean up, the video of the wisdom of all deleted, suddenly remembered that I learned the recursive traversal directory, as well as delete files and folders, then I can also try to delete the recursive video Ah ~

Well, think about the action immediately, I first put the recursive traversal of the function of the directory, and then because of fear of some unexpected errors, write a small script to try to delete a separate video, but because the video name is Chinese, can not be deleted, I go to the Internet to check information, The discovery needs to use an encoded conversion function iconv (), and then it succeeds. After I deleted the recursive function, I found that the system exploded two errors, saying that my iconv () and unlink () were not used correctly. I've been debugging a lot of times. To this evening, I asked the counselor, the original reason for the error is that I first put the path of the file to be pieced together before the conversion code, but because the directory (UTF-8) and the Chinese file name (GBK) uses the same encoding, so the ICONV () conversion is unsuccessful. The final solution is to first convert the directory to GBK, and then together with the Chinese file name, you can.

Then I think of a word: great programmers are lazy.
