When you use files stored in one of Microsoft cloud services, Office has a feature called AutoSave that automatically save changes to your document. This feature can slow down UpSlide's Update All feature.
What is AutoSave?
AutoSave is available in Excel, Word, and PowerPoint for Office 2016+. It saves your file automatically whenever you make changes to it. Unless your IT has a different policy, AutoSave is enabled by default in Microsoft 365 when a file is stored on OneDrive, OneDrive for Business, or SharePoint Online.
Since AutoSave saves your files automatically, it can slow down UpSlide's Link Update feature, especially when your files are large and when you have many links to update. This happens because Microsoft Office has to pause UpSlide several times to save the "changes".
How can I make Update All faster?
UpSlide v6.6.17+, we introduced a fix to mitigate the issue. When updating more than 100 links at once, UpSlide will temporarily turn off the AutoSave feature for your files and restore it at the end of the Update All process.
If you are on an older version, or if you experience low performances when updating fewer than 100 links at once, please try to turn off AutoSave on your files (on both Excel and PowerPoint/Word sides)
