The platform has an attachment size limit of 10MB - you may find that files like PowerPoints often exceed this so in these circumstances converting to a PDF can offer an agreeable solution. However, please bear in mind if you attach large cumulative amounts of data to a Record(s), you may experience a reduction in response times.
Note: In rare cases when large-sized images are used for things like homepages, display issues can occur. If you are experiencing this then please get in touch with our support team for a satisfactory resolution.
Note: There is an acceptable use policy on total file storage on a site. The Softools platform is not meant to be used as a file storage repository. Attachments should only support the process being managed by a Softools Application
