Aconex doesn't limit the size of files you can upload, send, or transmit, so in theory, you can upload any file size. This applies to zipped and non-zipped files. However, some browsers, as opposed to Aconex itself, do limit the upload file size. See below for more information on browser limits. Also, if your bandwidth is limited, it can take longer to upload files.
If you’re unable to upload a file to Aconex because of its size, try uploading it with a different browser, or try uploading your file at the end of the day, when fewer users may be trying to access your site's internet connection.
Note: If you need to view your uploaded files in the Online Viewer, keep in mind it supports files up to 1GB in size. See Online Viewer guidelines, supported file types, and fonts
