What is Telegram TDATA — Complete Guide to the Format

What is TDATA?

TDATA is the local data folder used by Telegram Desktop to store your session, encryption keys, and account data. When you log into Telegram Desktop, it creates a tdata folder inside the app's working directory. This folder contains everything needed to maintain your active session — without requiring you to re-enter your phone number or 2FA code.

What's Inside a TDATA Folder?

A typical TDATA folder includes:

• Session keys — encrypted authorization data that keeps you logged in
• Account settings — notification preferences, theme, language
• Cache data — recent messages, media thumbnails
• Device fingerprint — information about the device used for registration

The most critical files are the session keys. As long as these are valid, the account stays authorized — no SMS or password needed.

How is TDATA Used?

TDATA is widely used for:

• Account migration — move your Telegram session between computers by copying the tdata folder
• Multi-account management — run multiple Telegram Desktop instances, each with its own tdata folder
• Automation — some tools can work directly with tdata files for account operations
• Backup — save your tdata folder as a backup of your active session

TDATA vs Session+JSON

While TDATA is specific to Telegram Desktop, Session+JSON is a portable format used by automation libraries like Telethon and Pyrogram. Session+JSON files contain the same authorization data but in a standardized JSON format that's easier to use with scripts and bots.

Many sellers (including Accs Trading) provide accounts in both formats — so you can choose whichever fits your workflow. Use TDATA if you work with Telegram Desktop clients, or Session+JSON if you prefer automation tools.

How to Use a TDATA File

1. Download and extract the TDATA archive
2. Locate your Telegram Desktop installation folder
3. Replace the existing tdata folder (or create a new portable instance)
4. Launch Telegram Desktop — you should be logged into the account
5. Important: Always use a proxy matching the account's country to avoid bans

Tips for Working with TDATA

• Always use private proxies — one IP per account, matching the registration country
• Don't log into the same account from multiple devices simultaneously
• Warm up new accounts gradually — don't send mass messages immediately
• Keep backups of working tdata folders
