Understand the Maximum File Size You Can Upload to Box

The maximum file size limit for uploads to Box varies depending on your account type:

For more details, please refer to our pricing comparison page.

To confirm the file size limit for your account, log into Box. In the upper-right-hand corner, click your account icon. From the menu that displays, click Account Settings. On the page that displays, scroll down to the Account details section. Your Max file size is listed in this section.

Be aware shared folders enforce the file size limit that applies to the Folder Owner's plan, regardless of whether any of the collaborators within the folder have a higher limit. 
Here's an example:  Someone with a business account uploads files to a shared folder owned by someone with a free Box account. In this case, the business account holder is limited to uploads of 250 MB or fewer, since the folder belongs to the free account holder.
Alternatively, a free user collaborating on a folder owned by an Enterprise User can upload files of up to 15 GB in size in this folder.

Size Limits in Internet Explorer

Internet Explorer applies upload and download limits that supersede Box account-level upload limits. Anyone accessing Box through Internet Explorer versions 6, 7, and 8 can upload files up to 2 GB in size. Anyone on Internet Explorer versions 9, 10, and 11 can upload files up to 4 GB in size. For more information, please refer to Microsoft's official documentation. Note: Folder uploads on IE 11 are no longer officially supported, and functionality will be removed December 27, 2019.
