Check file upload limits and supported behavior
See the Files browser limits, supported file behavior, and steps for a rejected upload.
The Files browser accepts many kinds of files. Check these limits before you start a large upload.
What are the Files browser limits?
- You can add up to 100 files in one upload.
- Each file can be up to 2.1 GB.
- The uploader does not limit you to a short list of file types.
These numbers apply to the main Files browser. An attachment area in another part of Sydnee may have a different limit.
Does every file have a preview?
No. Images, PDFs, videos, and audio have an inline viewer. Another file type may show No preview available. You can still download it and open it in the right app.
Being allowed to upload a file does not promise that the browser can preview it.
What access do you need?
A team member can upload at the account's root Files level or in a regular folder. A client can also upload at the root. Inside a folder, the client needs Full Access. Uploading is blocked in a folder with View Only or Hidden access.
Uploads are unavailable in Recent, Starred, and Deliverables. Open the account's root Files area or a regular folder first.
Why was an upload rejected?
Check these causes in order:
- One file is larger than 2.1 GB.
- You selected more than 100 files.
- You do not have Full Access to the destination.
- You started from a view that does not accept uploads.
- Your sign-in session ended.
- Your network stopped during the upload.
Remove the file that breaks a limit or split the upload into smaller groups. Then use the uploader's retry action. If the session ended, refresh the page and sign in again before retrying.
What happens after an interrupted upload?
Check the destination folder before starting again. A file that finished can already be there even when another file failed. Retry only the missing or failed items to avoid duplicates.
What does your client see?
The client sees a completed upload only when they can access its folder. A successful upload does not change the folder's client access.
