Read the instructions first, then check the file extension
TData, Session and JSON describe different forms of data. TData is typically a related directory, Session is the session file used by an application, and JSON usually stores configuration or metadata. You cannot determine completeness, compatibility with all clients, or convertibility between them based on the file extension alone.
If a product explicitly provides accompanying files, keep the corresponding files and directories for each account. Renaming files, copying only part of a directory, or losing paired data may prevent use according to the original instructions.
Download complete does not equal acceptance
Check whether files can be completely saved, whether archives can be opened, and whether the number of accounts and file pairings match what was promised. Then verify the relevant client and verification data according to the instructions. File existence and successful login are two separate checks.
If downloads fail or formats are missing, retain the order, the file names and the error timestamps and resolve via order communication; when sharing screenshots publicly, hide numbers, passwords, verification codes and session contents.
Files do not equal long-term control of the phone number
Possessing session files does not mean you also control the phone number, recovery email, or two-factor authentication (2FA) password. If those capabilities are required, they must be confirmed item by item in the product description.
Web-based verification code functionality is also a separate condition and is only available when the order supports it. Do not treat file format labels as a guarantee of support for all clients or future verification needs.
Specification comparison
| Item | Meaning | What to verify |
|---|---|---|

| Compressed archive | File package container | Account count, directory and pairing integrity |

FAQ
Can I simply rename a Session to TData?
No. Renaming does not convert the file structure; use according to the explicitly supported method.
Is a JSON file itself a complete account?
Not necessarily. It may be just configuration; verify all files and fields promised by the product.
