Content version 745 added the 'Linux' file type to PAN-OS 8.0
Note: When the default size limit is changed by a new content release and if the maximum size limit is increased by the change, you will need to perform following steps in order to reflect the change to the internal queue size that the firewall has. (Details below.)

1. Review and change desired file size limits in the WildFire setting. (Device > Setup > WildFire)
2. Config commit

Caveat: Before files are uploaded to WildFire cloud, they are stored in an internal queue on the firewall. The capacity size varies depending on the firewall platform and the number of files that the firewall can store is calculated based on the maximum size limit among all the file types except APK. Please take note of this and change the value with care when you increase the size limit.

• Take note of max size among all file types except APK.
• Check the capacity by model: WildFire Administrator's Guide, Firewall File-Forwarding Capacity by Model
• Calculate your queue usage. [capacity] / [max size]
• Run show wildfire disk-usage command and compare the File Limit with the value of step 3 above.

For example, the capacity of PA-200 platform is 100MB, and when the max size is 10MB, the File limit becomes 100 / 10 = 10.

admin@PA-200> show wildfire disk-usage


Disk usage for wildfire:
Total disk usage:                            0
Total temporary files:                       0
File limit:          10 (Global), 10 (Channel)

 If the command shows different value, please follow the steps above (1 & 2) to reflect the change.
