Is there a size and/or page limitation for PDFs uploaded to tFLOW?

tFLOW > *tFLOW FAQs
The file size limitations are 200 inches max size (PDF limitation) and 1.9 GB file size, There is no page limitation, but there is a timeout on the server of 15 minutes.  If a file takes longer than 15 minutes to process, the server will stop the process.  If you have a very large file using a complicated script, then it is recommended that you split the file into parts.
