I finished playing games at 1 am this morning, and found out that I can use software to transfer files and software from the C drive to the D drive on TikTok. I tried it out, but the software unexpectedly crashed. It took me three hours to fix it until 4 am. I didn't expect that when I opened my computer this afternoon, the system crashed directly, it was so slow, I had to reinstall the system again (resetting the computer didn't work, I tried it myself). I just fixed it now, it's better not to mess around in the future. ☹️
