17.00.90 Creating archive.pa with Optimise strong. file.tar.gz and file.tgz are treated differently when they are in fact exactly the same
-
When creating a .pa archive using optimise strong which contains various files types I noticed that file.tar.gz and file.tgz are treated differently when they are in fact exactly the same and should be treated identically.

cool - so what method is used for each? And which one gets better compression?
-
Until @Brian-Gregory answers, I did a quick test, and can confirm his point.
For the same file, tar.gz is compressed, while tgz not.

Sorry. Wrong image:

@nikkho sweet, so whats the compression like for the one being reflated? try individual file compression with .tar.gz one. I wonder how it compares to original one. Is it extra 8% or?

It can be a huge improvement when there are a lot of them in a solid archive:

Did a simple test. Files were from Volkov Commander: https://vvv.kiev.ua/download/vc49908a.zip
I extracted them, and compressed as a tar.gz in PA. Then I copied it to a same file with tgz extension.
Now, added both onto separate archives:98.113 vc49908a.tar.gz.pa
100.103 vc49908a.tgz
100.103 vc49908a.tar.gz
100.685 vc49908a.tgz.pa
106.255 vc49908a.zip

@spwolf .tar.gz is handled like a zip file which I think is correct because it gives good results. While .tgz is, I think, handled like an unknown file type.

Agree.

yes, we use reflate for tar.gz and should be with tgz too⌠reflate âunpacksâ deflate streams and compresses them with plzma instead of deflate⌠so result is always going to be better, how much is determined by the data inside. If it is something very compressible, then result is going to be much better.

@spwolf Why canât I upload PNG images any more?
-
@Brian-Gregory apparently some bug with this version of forums, try using upload button or paste (not sure which one are you trying)
-
@spwolf Paste how? Iâm using the upload image button.
-
@Brian-Gregory copy it first and then ctrl-p into the post you are writing⌠one of these works, sometimes both⌠discovered last week by pierrbe⌠there is new version out, we will update it in the next few days, likely it will solve the problem. Thanks!
-
@spwolf I donât see how ctrl-p is suddenly not gong to act as the print command.
-
@Brian-Gregory obviously you are much more rested than me last night so you would use ctrl-v
-
@spwolf But nothing happens with ctrl-v or right click paste. Does it have to be a certain kind of image in the clipboard? Or a certain web browser? Iâm using Google Chrome.
-
open it in image viewer, copy-c and then copy-v to the post replyâŚ
it should work in chrome right click> copy image but I use Snap for captures and it automatically opens up there so I cant really test it.
I am sure @cetko will update forum software early next week so it should be fixed by then anyway.
-
@spwolf Nope. Doesnât work.
-
@Brian-Gregory . Very frustrating : sometimes it works but then suddenly ânot enough privilegesâ⌠I use the Edge Explorer Win10 and the standard Snipping Tool of Win10. (copy/past = ctrl-c / ctrl-v ctrl-p-printscreen !!?). I also tried to past first the snip in Word and then copy/past that image and other soft⌠but the problem is that communication third part soft.
I hope that the new update will avoid a nervous breakdown.
 Not enough privileges for this actionâŚ
