Hi Masatsugu UEHARA,

Welcome to the Box Community! I'm happy to help.

I ran a script to fix the file size count in your used storage and should be seeing the right file size count.

You can check this by going to your Box console> Account Settings>Account> Account Details> Storage ( used/total).

You can also check this article from our Box Support page about "Storage".

https://support.box.com/hc/en-us/articles/360043695334-Storage-Usage-Or-File-Count-In-My-Account-Is-Incorrect

Box Support is able to run a script for specific end-users’ accounts to fix the data inaccuracy issues around user storage size, folder size, and file counts. Please note that while the issue may be fixed, we are unable to guarantee that the account will not be affected by the issue again - particularly for users with massive amounts of content.

Best,

Thank you !!

Once the file size was normalized, I re-uploaded the file. But then I got an error, so I deleted all the files again and set them to zero. Now the file is zero, but 4.2G is in use. Please correct it.
