Hi Chae Won Ha,
Thank you for reaching out to Microsoft Community Support.
According to this issue, these restrictions have been like this for a long time. There are actually 2 ways you could try:
- Change the file name to not contain square symbol [ ]. You could use script to do it in a mass number.
- There are some suggestions (not from Microsoft) on using a different set of characters which look like the same to the restricted character. But in reality, when it comes to pathing in Windows, it will look totally different as they are not the original symbol you would like to use.
Let me know if you have any further questions.
Sincerely,
Austin H - MSFT | Microsoft Community Support Specialist
