How to resume a download use '.aria2' file

[iahu]

Can I resume a download task use '.aria2' file ?

[tatsuhiro-t]

aria2 creates a file whose name is the same as the file you are downloading and has a suffix ".aria2" (e.g., foo.txt.aria2). It is called control file.
It contains all information to resume download. Note that control file must exist in the same directory with the downloading file.

Thanks @tatsuhiro-t . I really searched how to do the resume job, but could not got a example.
Could you give a example usage of it for me ?
Thanks again.

When you hit ctrl-C while downloading is still in progress, aria2 leaves control file. Running the same command line, aria2 starts resuming last download.

Is it possible to restart the download without the original link, but only the .aria2 file? I want to resume my torrent and can't find the tracker...

[tatsuhiro-t]

Changing tracker is no problem as long as the info hash stays the same.

[HaleTom]

How do I use the info hash in the .aria2 to resume the download without finding a new magnet/download link?

[tatsuhiro-t]

https://aria2.github.io/manual/en/html/technical-notes.html describes the format of .aria2 control file.
Once the info hash is obtained, then creating magnet link is easy.

I think @HaleTom is looking for a command line option or something similar to resume a download without knowing the original download link, using only the .aria2 file.

[HaleTom]

@IamCarbonMan Yup, a user shouldn't need to dig into a file-format specification to resume a magnet download.

I'm also looking for the solution of resume without link, please tell me if anyone knows. Thank you!

@HaleTom That is exactly what I thought .aria2 files were supposed to do.

UNIX-like systems users are privileged in this case, because the majority of them use bash by default that comes with history and it's pretty easy to re-enter the original command to resume your download.

What about those poor Windows users?

Indeed it would be more than awesome to have such an option by default as you have suggested.

What it would be nice, would be to have something like a new flag that builds config settings for each download:

aria2c --build-config <magnet-link>

After you interrupt it and want to resume, all you must do would be something like:

aria2c --use-config <aria2-file>.aria2

This config should reside in the same location where the file is downloaded and as soon as the file gets downloaded successfully to get deleted automatically.

@tatsuhiro-t Does it sound silly as an idea?

Hi @HaleTom , I write a tools to transform .aria2 file to a magnet link http://alphatr.github.io/aria2-reader.html

@stefanos82 I use uget as a front-end to aria2c, so I can't use my bash history :(

[stefanos82]

@HaleTom no worries.

May I ask what operating system are you using? I could suggest an alternative to your issue as a workaround.
