?Partial RAR-file can nolonger be opend

[habell]

In version 8.01 is was possible to view partially downloaded multipart rar-files.
In version 8.50 is it no longer possible. It gives an error that the rar is not complete.
The fact that it is not complete, is correct. But that does not mean it can't be opend.
How can this be fixed? I reverted back to 8.01 for this feature.

Greatz,
Habell

Same here.
For what it's good for: sometimes I download large packed files on a slow internet connection. And it's useful to see the compressed file content before waiting a few hours to be completely downloaded.

BTW, this would be useful for incomplete zip files also.

Christian has to use what the unrar.dll from rarlab provides.
You have to live with it as long as no new version of this DLLs supports what you like.
Please search forum next time and you will find a lot of information about that topic.

You're right.
But when I saw this topic I thought the author already searched. Sorry, I should of checked anyway.
And thank you for the link and info.

Yes, I tested unrar.dll in Delphi 7 and indeed is asking for the next volume when listing the archive.
But I noticed one thing: before asking for the next volume it shows the name of the packed files from the volume.

All volumes (rar 5 archive):

Code: Select all

Archive test.part01.rar

Volume:          yes
Comment:         no
Locked:          no
Solid:           no
New naming:      yes
Authenticity:    no
Recovery:        no
Encr.headers:    no
First volume:    yes
---------------------------

File                                          Size
--------------------------------------------------

mobile-upgrade-m-6-3-4-setup.exe           9915755
onetouch-2001-user-manual-english.pdf      6593625

Just the first 1.44 MB volume (from 12 volumes):

Code: Select all

Archive test.part01.rar

Volume:          yes
Comment:         no
Locked:          no
Solid:           no
New naming:      yes
Authenticity:    no
Recovery:        no
Encr.headers:    no
First volume:    yes
---------------------------

File                                          Size
--------------------------------------------------
Alcatel-2001x_1383296206.pdf               4303021
Insert disk with test.part02.rar and press 'Enter' or enter 'Q' to exit

TC could use this to display the content of the volume.
When the dll function is returning the RAR_VOL_ASK (0) code, TC will check for the next volume; if it doesn't exist, it displays the info it's got from the first volume(s).

This is not a bug. TC 8.5 now shows the content of ALL parts of a RAR, not just the contents of the part you try to open. When a part is missing, TC will show an error - and then if you click OK, will show the contents up to that missing part.

[Cosmin3]

Yes, but it's very annoying to have to use Ctrl+PageDown/Return, click on Cancel, and in next window click on OK EVERY TIME. And to hear that beep every time.
In 8.01 it was simpler, just Ctrl+PageDown/Return.

The idea is: I ALREADY KNOW some volume(s) are missing, it's no need for TC to warn me. Especially with 2 windows and a beep.

Then go to www.rarlab.com and tell them to fix the damn dll - perhaps if enough people complain they listen....

[Cosmin3]

@Sir_SiLvA
In my Delphi 7 tests I saw the problem is not with the dll.
You can easily dismiss the request of the dll function (for the next volume) without showing the request to the user but keeping and showing the data collected so far.

[ghisler(Author)]

Yes, it can be dismissed, but how could the user then choose a different location (e.g. second USB stick) or swap media?

[Cosmin3]

In today's computers these sort of situations are rarely meet. Most of the times when the user wants to see what's in the archive, all the (available) volumes will be in the same folder.
But, to make everybody happy, you can add a "Don't ask/show next time" checkbox in the first window. If it's ticked, no message is shown (and no beep).

The user can revert this if you add a checkbox for this somewhere in Options (in the Packer section for example).

As for the second (error/warning) message + the beep, they are useless since the user already know he/she clicked on Cancel.

This is a related topic concerning the use of multi-volume rar archives:
http://www.ghisler.ch/board/viewtopic.php?t=39301

I support the above suggestions to dismiss the request of the dll function, when a certain option is enabled (e.g. ExpertMode=1)

[Packer]
ExpertMode=1

Please let the expert users remain experts, and stop this annoying behaviour (be consistent with v8.01 and earlier). Thank you!

[Cosmin3]

Wow, on this forum telling the truth and giving suggestions is considered "annoying".
Well, if mr Ghisler feels the same way and wants me to shut up, I'll go elsewhere.
This problem is not so critical, and the internet is very big, you know

You must be misunderstanding, users find the dialogs annoying, not you.

For the first beta of TC 8.51, I have implemented a small amelioration: When the "Next volume" dialog is cancelled, TC will show the archive contents without further error messages. This way the user is alerted about the partial file, but only has to deal with one dialog.

[atomix]

Cosmin3, you clearly missunderstood my post. I am actually fully supporting your suggestion, and we are on the same page.

As Christian mentioned already, it is the behavior of TC 8.50 (showing multiple errors) which is annoying and also inconsistent with the previous TC versions, up to 8.01.

Christian, many thanks for the 1st amelioration, I very much appreciate it. Now if you could just go another step further, to eliminate also the remaining extra dialog (for expert users), that would be truly great.
