File Uploads Size

OpenBoxes supports configurable size limits. You might lower the maxFileSize for security reasons i.e. to prevent DDoS attacks. You might increase maxFileSize to attach high-resolution images and documents (say, to a product or shipment) or to upload large datasets through the data import feature.

Defaults

The default max file size is 2097152 (~2MB). 

grails:
    controllers:
        upload:
            maxFileSize: 2097152  # 2MB max file size
            maxRequestSize: 2097152  # 2MB max request size

Overriding

If you ever need to increase or decrease the max file size just calculate the bytes for the desired max size.

grails:
    controllers:
        upload:
            maxFileSize: 10485760  # 10MB
            maxRequestSize: 10485760  # 10MB

Tip

In case it's not clear, the unit of measure conversion formula for converting from MB to bytes looks like this. 

= 2 MB * 1024 Kb/MB * 1024 bytes/kb 
= 2 * 1024 * 1024 bytes 
= 2097152 bytes
If you wanted to increase the size to 10MB 
= 10 MB * 1024 kb/MB * 1024 bytes/kb
= 10 * 1024 * 1024 bytes
= 10485760 bytes
If you want to allow GBs, then multiply by another 1024 (1024 MB/GB) 
= 2 GB * 1024 MB/GB * 1024 Kb/MB * 1024 bytes/kb 
= 2 * 1024 * 1024 * 1024 bytes 
= 2147483648 bytes
