QuickBooks is a premier accounting software that has made managing and handling business simple. But, like all the other software, QuickBooks too isn’t free from errors and glitches. One of the frequent issues that QuickBooks users face is QuickBooks Error Code 6000 304. This error occurs when a user tries to open a company file, or QuickBooks Desktop attempts to open a company file. Occurrence of an error in such cases denotes that your system lacks enough disk space to open the company file or the user working on QuickBooks Desktop has reached his quota.

You can change the location of the company file to hard disk with larger space, turn off disk quotas, and/or enhance the disk quota of the user account running QuickBooks to fix Error Code –6000, -304.
