Hi ​@narazaki_seito_0320 👋 Welcome to the Box Community! We’re only able to provide support in English—thank you for your understanding. To assist you, we’ve translated the content. Please reach out to us in English moving forward.

To investigate and assist you better, could you confirm the following details?:

• Who is the owner of the file?
• Were there other people who had access to the file?
  • Do they update or open it simultaneously?
• Does the issue still occur?
• Was the file accessed exclusively through Box Drive?
• Are there any error notifications on Box Drive?
• Can you check the following locations to see if the files appear there?
  • Mac: ~/Library/Application Support/Box/Box/unsyncedFiles
  • Windows: C:\users\[USERNAME]\AppData\Local\Box\Box\unsyncedFiles

Looking forward to your response! 😊
