Problem. For users at the free “personal” level, Box.com has a 250MB limit on the size of a file you can upload using their web interface. You can upgrade your account to the $15 per month plan to upload files of up to 2GB in size. However, those lucky enough to have received the 50GB of storage free-for-life plan will want to avoid getting locked into paying $180 a year just to upload the occasional large file.
Solution. If you use the Box.com synchronization feature, the 250MB limit isn’t an issue. So, you can upload those occasional large files and retain your free membership level.
Update. The above work-around was previously an option. However, as of August 2013, Box.com will not synchronize files of a size that exceed your plan’s upload file size limit.
