A client sends over a 400 MB set of drawings, a video walkthrough or a full audit pack. Salesforce happily accepts the upload. But when that file needs to go on to SharePoint, where the rest of your documents live, size suddenly matters. Sound familiar? In this blog, we’ll explain why large files have been a challenge for Salesforce–SharePoint integrations, and how File 365 now moves files of up to 2 GB to SharePoint.
Salesforce can handle large files. So what was the problem?
Uploading a large file to a record in Salesforce has never been the issue. The challenge starts when an app needs to do something with that file, such as moving it to SharePoint. Apps like File 365 run on Apex, Salesforce’s own programming language, and Apex has a memory limit: the heap size limit. A file has to fit within that limit to be processed in one go. For a long time, this meant File 365 could move files of up to 11 MB to SharePoint. With the Winter ’27 release, Salesforce raised that limit, and File 365 followed straight away: since then, files of up to 23 MB go to SharePoint without any problem.
Now even larger: sending files in parts
But a 400 MB set of drawings is still well beyond 23 MB. That is why File 365 version 5.0 goes one step further. Files larger than 23 MB are now sent to SharePoint in parts, in the background. Each part fits comfortably within the Apex limits, and SharePoint puts the file back together. The result: you can now move files of up to 2 GB from Salesforce to SharePoint.
Nothing changes for your users
Your users upload files just like they always have, straight from the Salesforce record. They don’t have to keep the page open or wait for the upload to finish: File 365 takes care of it in the background. Once it is in SharePoint, the file is still one click away from the right Salesforce record. And if you ever need to retry a large file from the Gallery, that retry runs in the background too.
Where large files matter most
For some teams, large files are part of everyday work. Think of technical drawings and site photos in engineering and construction, aircraft and asset documentation in leasing, or complete case files and audit packs in the public sector. These files can now live in SharePoint as well, together with all your other documents.
Switch it on once
Large file uploads are available from version 5.0. Your administrator switches them on once, under “Large file uploads” on the Connection Setup page in the File 365 Administration app. After that, it simply works for everyone.
