View and download course files from TeraBox without signing in

Every term your instructor hands out a TeraBox link with the readings, slides and lecture recordings.

The download is never one click: you have to walk nested folders one level at a time, and the same share can hide under any of eight TeraBox domains.

Tested 6 August 2026 157 share links By TeraSaver With Love

Short answer. For course materials shared via TeraBox, paste the share link into TeraSaver. It shows the file list without sign-in or app install, and you download straight from TeraBox. In tests on 6 August 2026, 92.8% of 157 links opened; a 307 MB file downloaded in 4 m 49 s.

What you need first

You have the full TeraBox share link from your course page, including the code after /s/ or in the surl parameter.
The share is not password-protected. A password set by the owner cannot be bypassed, so that kind of link is impossible to open without the password.
You have link allowance for today: 3 anonymous links or 10 with a free account. The counter resets daily.

Step by step

Copy the course share link

Get the exact URL your instructor posted. The share code appears as a path segment after /s/ or as a surl query parameter, and a leading 1 often does not belong to the code. Paste the complete address into TeraSaver rather than retyping it.
Paste it into TeraSaver

No login is required because file metadata for a public share is readable without credentials. Each anonymous day allows 3 links, or 10 with a free account. If you exceed the limit, wait for the daily reset or sign in.
Wait for the file list

After submitting, the tool resolves the share and lists its contents. In our test of 157 links, the file list appeared in a median time of 2.7 seconds. If you see a 429, the source is rate limiting you and it clears after a short wait.
Open folders and select files

Course folders can nest several levels deep. TeraSaver walks one level at a time, so keep clicking into folders until you reach the materials. A 401 error means the owner has set a password; a 410 error means the share was deleted at the source.
Start the download and wait

Choose the file and begin. The final address is served by TeraBox's CDN, so the file travels straight to your device and never passes through TeraSaver. On our test connection, a 307 MB download took a median 4 m 49 s, about 8.5 MB/s.

Why this works

TeraSaver works because a public TeraBox share exposes its file metadata without any sign-in. Pasting a link lets TeraSaver read the share code from the path segment after /s/ or from the surl parameter, then fetch the folder tree. That list is metadata, so nothing heavy is transferred to show it. The final download address is served by the source CDN. The file travels straight from TeraBox to your device and never passes through TeraSaver. That CDN answers range requests, which is what lets a player seek and a download manager resume. Share codes often include a leading 1 that is not part of the real code, and the same share can appear under any of eight different domains, all handled the same way.

How these figures are produced: our testing method.

When it does not work

This link is password protected.

The share owner set a password on it; error code PASSWORD_REQUIRED with HTTP 401 indicates the share cannot be read without that password.

Ask the person who shared the link for the password. Nothing can open this share without it; no tool can bypass the password.

This file has been deleted at the source.

The share owner removed the file, so the share now returns HTTP 410 (SHARE_DELETED).

Contact the owner to re-upload the file or send a new share link. A deleted share cannot be recovered by any tool.

Too many requests. Please try again shortly.

You have hit a rate limit. Error code RATE_LIMITED with HTTP 429 means the source is telling you to slow down. This page allows 3 anonymous links per day and 10 per day with a free account.

Wait for the rate limit to clear on its own, then try again. If you have a free account, the daily allowance is 10 links.

The source took too long to respond.

The upstream server did not answer in time; error code UPSTREAM_TIMEOUT with HTTP 504 means the source is delayed, not your connection.

Wait a bit and retry. This is temporary and usually clears on its own.

Limits worth knowing

The measured success rate is 92.8%: of 157 share links tested, not every link opened. If a link fails, it is not always something you can fix.
Anonymous use is capped at 3 links per day; a free account raises that to 10. If you need to access more shares than that in one day, this page is not sufficient.
Downloads do not resume on their own if your connection drops. The final CDN address supports range requests, so a download manager that uses range requests is the better tool for large files or unstable connections.

Safety, privacy and rights

TeraSaver sees the file list and the metadata needed to produce it, and nothing else. It never asks for TeraBox credentials, so there are no passwords to store or see. A share locked with a password cannot be opened without that password, and if the owner deletes the file, the share stops working. The file download goes from the source CDN straight to your device, not through TeraSaver. Access control sits with the share owner.

Questions people ask

Can I download without installing the TeraBox app?

Yes, TeraSaver opens share links in a browser, so no app is needed. File metadata for a public share is readable without signing in, and the final file comes straight from TeraBox's CDN to your device. We tested on Android, iOS and desktop.

How do I download a whole folder of course materials?

TeraSaver walks nested folders one level at a time, so you can open a folder and see its contents. You select the files you need, and each download goes directly from the source. If a folder has many files, you may need to open each subfolder.

Will a big file download quickly?

In our test of a 307 MB file, the median download took 4 m 49 s at a sustained 8.5 MB/s. Your actual speed depends on your connection, and range requests let you resume a stalled download. We saw a 92.8% success rate across 157 links.

Can I play a course video without downloading it first?

Yes, the final CDN address answers range requests, which lets a player seek while streaming. TeraSaver gives you the direct link, so you can use it in a player that supports range requests. This works on Android, iOS and desktop, and you don't need to sign in to get the link.

How many TeraBox links can I open each day?

The free anonymous limit is 3 links per day. If you create a free account and sign in, that goes up to 10 links daily. The source timeout is 27 seconds, so a slow share may not load if it takes longer.
