For security reasons, our CivicPlus file size limit for any single upload area, such as upload to Form Center and single upload in Archive Center, is 20 MB.
In any module that allows users to batch upload files, such as the Document Center, Image Repository, and Multiple Upload in Archive Center, there is no limit to the size per document. However, the size limit for the window is 1 GB. Clients with the CivicPlus Platinum Security Package have a size limit of 500 MB.
If a file exceeds this limit, it is recommended to break the uploads into different batches and upload only a handful at a time instead of all at once.
