How to Upload or Send Large TS Video Files Successfully
Question details
The user needs to share a large ZIP file containing TS videos and images, but the upload process takes several hours and frequently results in incomplete transfers.

- Device & OS
- not provided
- Scenario
- Uploading a large ZIP archive containing high-resolution TS video files and images over a standard internet connection.
- Observed behavior
- The upload takes an excessive amount of time (often several hours) and fails to complete properly, sometimes leaving only thumbnails instead of the full video files.
Before attempting to upload large TS video files, perform a network speed test to verify your actual upload speed and ensure your connection is stable enough for long transfers.
Optimize Network and Use a Robust File-Transfer Client
For files that take hours to upload, using a dedicated desktop cloud application is far more reliable than a standard browser upload.
Standard web browsers are highly prone to session timeouts and connection drops during long upload sessions. Dedicated syncing applications can handle intermittent network drops and automatically resume uploads without starting over from scratch.
With a low upload speed (e.g., 1 Mbps), a 200 MB file will take over 30 minutes under ideal conditions. Maximizing connection stability is critical.
Connect your device directly to your router using an Ethernet cable to minimize wireless interference and packet loss.
Download and install a dedicated desktop client for a reliable cloud service (such as Dropbox, WPS Cloud, or Google Drive) rather than uploading through a web browser.
Drag and drop your large ZIP archive containing the TS videos into the local cloud sync folder created on your computer.
Leave the application running in the background. If your connection drops, the desktop client will automatically resume the transfer once the internet is restored.

Split Your ZIP Archive into Smaller Volumes
If your internet connection has a strictly low upload speed limit, breaking the archive into smaller segments prevents a single connection drop from ruining the entire upload progress.
Share Large Files Easily Using WPS Office Cloud
WPS Office includes built-in cloud storage (WPS Cloud) that allows you to reliably upload, manage, and share large files, including ZIP archives and TS videos, via secure shareable links.
- 1. Sign in to WPS Office: Open the WPS Office desktop client and sign in to your WPS account.
- 2. Access WPS Cloud: Navigate to the 'Cloud' or 'My Cloud' tab located on the left-side panel of the home screen.
- 3. Upload your file: Click the 'Upload' button and select your large ZIP file or TS video file from your local storage to begin a stable sync process.
- 4. Generate a sharing link: Once the upload is fully complete, right-click the file, select 'Share', and copy the generated link to send to your recipients.

Frequently Asked Questions
Why do my large TS video uploads keep failing halfway through?
Uploads often fail due to unstable internet connections or session timeouts on the hosting server. Web browsers struggle to maintain long, continuous connections over slow networks, causing the upload to abort. Using a desktop syncing app can resolve this by allowing interrupted uploads to resume.
What is a good upload speed for large video files?
While it depends entirely on the file size, an upload speed of at least 10 Mbps is recommended for transferring large video archives efficiently. Speeds near 1 Mbps can take over 30 minutes just to upload 200 MB, increasing the chance of connection drops.
Can I resume an interrupted file upload?
This depends on the platform and method used. Dedicated cloud sync desktop applications usually support resumable uploads automatically. However, standard uploads done through a web browser typically do not, requiring you to start over from the beginning if a failure occurs.
