Download Videos from a Restricted Telegram Channel or Group

To download videos from a Restricted Telegram channel (where saving, forwarding, and screenshots are disabled) using Unigram, you must retrieve the file directly from the application's local cache directory. Since Unigram is a Universal Windows Platform (UWP) app, it stores downloaded media in a sandboxed specific folder within your AppData. You cannot use the Save As button; you must manually copy the cached file and add the .mp4 extension.

Why This Matters
Telegram's "Restrict Saving Content" feature is a client-side restriction. When a channel admin enables this, the server sends a flag to your Unigram client instructing it to hide the Save, Forward, and Export buttons.

However, for you to watch the video, the data must be downloaded to your computer. There is no such thing as "streaming" without data transfer. Unigram downloads the video stream into a temporary cache folder so your video player can render it. The hack here involves bypassing the user interface (which is restricted) and accessing the file system (which contains the raw data). Unlike the standard Telegram Desktop (Win32) app which encrypts its temp cache more aggressively, Unigram (UWP) often leaves these files accessible in the LocalState directory, albeit with obscured filenames.

What You Need Before Starting
Checklist

• Unigram for Windows: Installed via the Microsoft Store.
• VLC Media Player: Windows Media Player often fails to play files with manually added headers/extensions. VLC is more robust for testing.
• Hidden Requirement (File Extensions Visible): You must configure Windows Explorer to show file extensions so you can properly rename the file later.

What You Should Do
Step-by-Step Guide

1. Buffer the Video Completely
Open Unigram and navigate to the restricted channel. Click the play button on the video you want to download. Allow the white buffering bar to reach the very end.
Note: If the video is not fully buffered, you will only extract a partial, corrupted file.

2. Open the UWP Packages Directory
You need to navigate to the deep system folder where Windows Store apps live. Press Windows Key + R on your keyboard. Paste the following path and hit Enter:
%localappdata%\Packages

3. Locate the Unigram Folder
In this folder, look for a directory named strictly like the Unigram package ID. Find the folder named:
UnigramHQ.Unigram_rr15e9jca7a84
(The random string at the end may vary slightly, but it always starts with UnigramHQ). Open it.

4. Navigate to LocalState
This is where the app stores user data. Navigate through the folders:
LocalState > 0 (or your numeric User ID) > videos
Tip: If you do not see a 'videos' folder, stay in the 'LocalState' folder and proceed to the next step using the Search method.

5. Identify the Video File
The file will likely not have a friendly name like Video.mp4. It will be a random string of numbers. Right-click empty space > Sort by > Date modified. Look for the most recent file that matches the approximate size of the video (e.g., 50MB - 200MB).

6. Copy and Rename
Crucial: Do not move or rename the file inside this folder, or Unigram may crash/lose data.
Copy the file and Paste it to your Desktop.
Right-click the pasted file > Rename.
Add .mp4 to the end of the filename (Example: Change 38473294 to 38473294.mp4).

7. Verify Playback
Open the new file with VLC Media Player. If the video plays but has no sound, or vice versa, the file might still be downloading. Wait and try again.

How It Works & Hidden Details
Universal Windows Platform (UWP) apps run in a sandbox. Unlike standard Windows apps that can dump temp files in the standard temp folder, UWP apps are forced to use their specific Package container.

When Unigram plays a video, it acts as a Direct Download to this container. Telegram's encryption for restricted channels is primarily Transport Layer encryption (between server and client). Once the file reaches the client and is assembled for playback, it often resides on the disk in a decrypted state because the built-in Windows media handling APIs require direct access to the stream.

However, sometimes Unigram does not append the .mp4 extension to these cached files to prevent them from automatically showing up in the Windows Photos or Movies & TV apps. By manually locating the file based on the timestamp (exactly when you watched it) and the file size, you are effectively bypassing the obfuscation.

Things to Watch Out For

• Automatic Cache Clearing: Unigram has an aggressive cache management setting. If you close the app, it might delete the temp file immediately to save space. Perform the extraction while Unigram is still open.
• Secret Chats vs. Restricted Channels: This method works for Public/Private Channels with "Restrict Saving" enabled. It does not work for "Secret Chats" (Green padlock). Secret Chat media is encrypted locally with a key that is only in the RAM, so the file on the disk is unreadable garbage data without the app context.
• File Extensions: If the renamed .mp4 does not play, try renaming it to .mkv. Some Telegram videos are encoded in Matroska format, though .mp4 is standard.

Frequently Asked Questions
Q: Can I use this method on the Android version of Unigram/Telegram?
A: No. Android 11+ restricts access to the Android/data folder where cached files live. This specific directory traversal is only easily possible on Windows.

Q: Why is the 'videos' folder empty?
A: You likely have "Stream without downloading" enabled or the cache path has shifted. Go to the parent LocalState folder and use the Windows Search bar to search for "size:>10mb" to find where the large file is hiding.

Q: Will the channel admin know I saved the video?
A: No. You are interacting with files already on your own hard drive. No signal is sent back to the Telegram server stating that you copied a file from your AppData folder.

Update: Additional Details & Recent Changes

• Package Name Variation:
  The specific package ID for Unigram has changed in recent Microsoft Store updates. If you cannot find a folder starting with "UnigramHQ", look for TelegramFZ-LLC.Unigram (Stable) or 38833FF26BA1D.UnigramPreview (Beta). The random string at the end varies by system.
• Web Client Alternative:
  For users finding the directory traversal difficult, note that in 2025/2026, the "Telegram Web K" and "Web A" clients (accessed via browser) are easier targets. Several browser extensions (like "TG Downloader") can hook into the video stream and force a download even on restricted channels, bypassing the need for file system mining entirely.
• HEVC Codec Issues:
  Telegram increasingly uses H.265 (HEVC) compression for high-quality videos. If your extracted file plays audio but shows a black screen in VLC, ensure you have the HEVC Video Extensions installed from the Microsoft Store, or use a player with built-in codecs like PotPlayer.

Find the folder named:
UnigramHQ.Unigram_rr15e9jca7a84

Update: Most modern installations now use the Package Family Name TelegramFZ-LLC.Unigram_.... Ensure you are looking for this folder if the UnigramHQ folder is missing.
