Hi @SUB_AU
Generally speaking, the company name is changed from within the Setup>>Company Information window. If the company file is stored online we do recommend going to Help>>Confirm Company File (that confirmation can be done online). This confirmation ensures that the name is reflected on our end as well.
If you are looking at changing the actual file name, it does depend on whether the file is online or offline:
- Online files - you want to take a backup of the online file (File>>Backup). Once that backup has been completed, restore that file locally on your computer with the required file name. When that name change process has occurred, you want to repeat the process again but this time backup the local file and restore online.
- Offline files - navigate to your library location within Windows Explorer and rename the file listed.
