This article describes how to upload and download files from Box, and contains FAQs and troubleshooting tips.
Drag files from your desktop to the files page in Box. Your files will be uploaded and will appear in the folder where you dropped them.
You can easily upload files or send attachments to a specific Box folder by email when you enable the Allow uploads to this folder via email option. You can then forward email attachments or send files to the email address generated for that folder to upload your files. If you decide to forward email attachments to the folder, only the attachments will be uploaded, not the content of the message.
For instructions on uploading files and folders from your mobile device, see the following articles:
The maximum file size limit for uploads to Box will vary depending on your account type:

To confirm the file size limit for your account, log into Box. Click on the arrow next to your name in the upper right-hand corner and choose Account Settings > Account. Your Max file size is listed under Account Details.
It's important to note that shared folders enforce the file size limit that applies to the Folder Owner's plan, whether or not any of the collaborators within the folder have a higher limit.
A Business account user is uploading files to a shared folder owned by a free user. The Business user will be limited to uploads that are no larger than 250MB since the folder is owned by a free user.
Internet Explorer applies upload and download limits that supersede Box account-level upload limits. Users accessing Box through Internet Explorer versions 6, 7, and 8 can upload files up to 2GB in size. Users on Internet Explorer versions 9, 10, and 11 can upload files up to 4GB in size. For more information, please refer to Microsoft's official documentation.
If you are on your All Files page and you are unable to click on the 'Upload' and 'New' buttons, it is likely that the administrator of your enterprise has restricted creating or uploading content at the root level for all managed users. You will be able to create subfolders within folders that your admin has granted you access to. If you would like another root level folder created for you, reach out to your admin and he or she can provision one for you.
If you're having trouble using the Folder Uploader on Box while using the Safari browser on your Mac, your Safari settings may be blocking the Java applet from running correctly. See this detailed troubleshooting article for exact steps on how to make this work.
Some files created on Apple operating systems (Mac OS X) are stored as packages, which is a folder that Mac OS X interprets as a single file.
To upload package files, you will need to use Box Sync 4.0+, or convert the package files so they are saved as a single file. See Apple's support documentation for more information on how to convert iWork package files to single files. Other applications may also offer the option to save these types of files as flat files, which can uploaded without using Box Sync.
Alternatively, you can right-click the file and compress it (save it as a .zip file) before uploading to Box.
See Mac Package Support for more information on uploading package files using Box Sync.
These steps only apply to Internet Explorer. Chrome and Firefox utilize HTML5 for Folder Uploads.
To resolve Upload Folders issues in Windows 7 with IE you will need to allow Java to run.
In Internet Explorer click Allow to let the folder uploader launch:
Click Run on the Java popup dialog:
If the steps above don't resolve the Upload Folders issue, please try uninstalling and reinstalling Java:

Slow upload speeds can have a variety of causes.
Box does not limit, throttle, cap, or shape upload bandwidth for individual files.
Box does perform processing on each file which can impact the total time it takes to complete an upload, particularly when uploading multiple files. But this does not limit the bits/second of your machine's connection to Box.
If you find that your upload is taking longer than it should, we have listed a few reasons that may affect upload speeds.
A Note on Kilobytes vs. Kilobits:
There is a difference between “Kb” (kilobit) and “KB” (kilobyte). One kilobyte is equal to eight kilobits. Internet service providers (ISP) often calculate and advertise upload and download speeds in terms of “Kbps” (kilobits per second) while Box uploads are calculated in terms of “KBps” (kilobytes per second). Therefore, if you are seeing browser upload speeds of 30 KBps this would be interpreted as 240 Kbps by your ISP.
Upload speed depends on your network connection and a component of this is bandwidth.
For business and enterprise accounts, Box has proprietary accelerator nodes that allow us to route your uploads through the fastest network route. To kick-start this feature, we suggest uploading approximately 14 files (between 2 and 6MB each) to your account, to initialize the accelerator node’s search for the best route. From there on out, your connection will route your 100MB+ filesize uploads through the fastest route to Box. It takes only a handful of uploads per week to keep the Box Accelerator optimally tuned for your whole office.
