Understanding SharePoint Online's File Size Limits

If you're working in the cloud with SharePoint Online, understanding the file limits is crucial to optimize your workspace and avoid any unexpected bottlenecks. With Microsoft's ever-evolving services, these limits can change, and it's important to stay updated. Let's delve into SharePoint Online's file limits, ensuring your data management strategies align with these constraints.

SharePoint's versatility expands from simple document storage to hosting intricate solutions, like team sites and portals. Knowing the platform's limitations can help you harness its full potential sustainably.

SharePoint Online Basic File Limits

Before diving deep, let's cover the fundamental file limits that apply across the board in SharePoint Online.

The primary limits include:

• Total storage per site collection: 25TB
• Maximum file size: 250GB
• Maximum single folder size: 250GB
• Number of files per folder: 30 million

Site Collection and Storage Quotas

A site collection is the smallest unit of SharePoint that can be assigned a quota. Understanding storage quotas can help manage your site collections' growth.

Quotas are set on the root site collection and can be 100GB, 250GB, 500GB, 1TB, 5TB, 20TB, and 25TB. Once a site collection approaches 80% of its quota, Microsoft sends notifications to site collection administrators and users.

SharePoint Online File Path Length

SharePoint Online supports file paths with a maximum length of 400 characters. This includes the file name and extension.

For instance, files saved in "C:\Users\User1\Documents\Project Documents\Meeting Notes\2022\January\Day1\File1.docx" would exceed the limit. To optimize your file structure, aim for shorter paths and names.

SharePoint Online Lists and Libraries

Lists and libraries in SharePoint Online have unique file limits to consider.

While calculating the number of files you can store in a list or library, consider these limits:

Lists

In SharePoint Online, the limit for list items is 30 million per list, and the maximum number of lists per site collection is 5 million.

However, keeping the number of items in a list below 5,000 is recommended to maintain performance and avoid long load times.

Libraries

Instead of list items, libraries contain files. The maximum number of files per library is 30 million.

Microsoft recommends adhering to the following limits for optimal performance:

1. Items per view: 5,000

Embracing SharePoint Online's file limits enables smooth collaboration and data management in your organization. Staying informed and adhering to these constraints ensures your team benefits from SharePoint's potent features without encountering any barriers.

Regularly review and adjust your data management strategies as your organization grows. With Microsoft continuously updating SharePoint's capabilities, there's always room to optimize your workspace and improve productivity.
