It reaches my proxy's speed limit, and the speed depends on whether you are a premium

tdl version

Basic Configs

The following command documents will not write basic configs. Please add the basic configs you need.

You should set the namespace when each command is executed:

tdl -n iyear
# or
export TDL_NS=iyear # recommended

(optional) Set the proxy. Only support socks now:

tdl --proxy socks5://localhost:1080
# or
export TDL_PROXY=socks5://localhost:1080 # recommended

(optional) Set ntp server host. If is empty, use system time:

tdl --ntp pool.ntp.org
# or
export TDL_NTP=pool.ntp.org # recommended

Login

When you first use tdl, you need to login to get a Telegram session

If you have official desktop clients locally, you can import existing sessions.

This may reduce the risk of blocking, but is unproven:

tdl login -d /path/to/Telegram # recommended

tdl login

Download

Please do not arbitrarily set too large threads and size.

The default value of options is consistent with official clients to reduce the risk of blocking.

If you need higher speed, set higher threads and size

For details: iyear#30

Advanced Options:

Flag	Default	Desc
`-t/--threads`	4	threads for transfer one item
`-s/--size`	128*1024 Bytes	part size for transfer, max is 512KiB
`-l/--limit`	2	max number of concurrent tasks

Download (protected) chat files from message urls:

tdl dl -u https://t.me/tdl/1 -u https://t.me/tdl/2

Download (protected) chat files from official desktop client exported JSON:

tdl dl -f result1.json -f result2.json

You can combine sources:

tdl dl -u https://t.me/tdl/1 -u https://t.me/tdl/2 -f result1.json -f result2.json

Download with 8 threads, 512KiB(MAX) part size, 4 concurrent tasks:

tdl dl -u https://t.me/tdl/1 -t 8 -s 524288 -l 4

Full examples:

tdl dl --debug --ntp pool.ntp.org -n iyear --proxy socks5://localhost:1080 -u https://t.me/tdl/1 -u https://t.me/tdl/2 -f result1.json -f result2.json -t 8 -s 262144 -l 4

Upload

Same instructions and advanced options as Download

Upload files to Saved Messages, exclude the specified file extensions:

tdl up -p /path/to/file -p /path/to/dir -e .so -e .tmp

Upload with 8 threads, 512KiB(MAX) part size, 4 concurrent tasks:

tdl up -p /path/to/file -t 8 -s 524288 -l 4

Full examples:

tdl up --debug --ntp pool.ntp.org -n iyear --proxy socks5://localhost:1080 -p /path/to/file -p /path/to/dir -e .so -e .tmp -t 8 -s 262144 -l 4

Backup

Backup or recover your data

Backup (Default: tdl-backup-<time>.zip):

tdl backup
# or specify the backup file path
tdl backup -d /path/to/backup.zip

Recover:

tdl recover -f /path/to/backup.zip

Chat Utilities

Some useful utils

What flags mean: flags

NAME	FLAG
TDL_NS	`-n/--ns`
TDL_PROXY	`--proxy`
TDL_DEBUG	`--debug`
TDL_SIZE	`-s/--size`
TDL_THREADS	`-t/--threads`
TDL_LIMIT	`-l/--limit`
TDL_NTP	`--ntp`

Best Practice

How to minimize the risk of blocking?

Login with the official client session.
Use the default download and upload options as possible. Do not set too large threads and size.
Do not use the same account to login on multiple devices at the same time.
Don't download or upload too many files at once.
Become a Telegram premium user. 😅

FAQ

Q: Is this a form of abuse?

A: No. The download and upload speed is limited by the server side. Since the speed of official clients usually does not reach the account limit, this tool was developed to download files at the highest possible speed.

Q: Will this result in a ban?

A: I am not sure. All operations do not involve dangerous actions such as actively sending messages to other people. But it's safer to use an unused account for download and upload operations.
