Q:  Is there a file size limit when opening and editing files in Xodo PDF Studio?

A:  Yes, the max size of a document that can be opened by Xodo PDF Studio is 2.147 GB. The technical reason for this is the max size of an array that Xodo PDF Studio can handle is (2^32 -1) bytes. This computes to 2,147,483,647 bytes (2.147 GB). This is a limitation that we are currently aware of in our desktop application.
