To update existing content in the library, it is best to use the replace content feature. This feature is great as it updates the content everywhere it is used on the site.
To replace content in the library, start by locating the file you would like to update. Click the three dots and select edit. Now, click replace file. This will show your file explorer on your device, and you can now select the document you would like to replace it with.
After this has been uploaded, click save changes.
This is how you can keep your content updated throughout Expanshare.
