Hi @William Wolfe ,
Welcome to our forum!
Of course, you can remove this data file. Just click "remove" above your screenshot. Do you have any concerns? If you are worried about data loss, it is recommended that you export items to a .pst file for backup before removing it.
In addition, considering that the screenshot you provided contains personal information, I have hidden it in order to avoid privacy disclosure. Please remember to hide your personal information before uploading.
