What features do you want in new format?

[spwolf]

Tell us what features you want from new format...

[spwolf]

Strong compression? Fast compression? PDF compression? Encryption? Multivolume? PAR-like recovery????

[amh209]

PDF compression would be nice. I send a lot of PDF files, so I would benefit from that one.

[TBGBe]

Are you developing a new compression format OR looking for a new format to be supported in PA

Yes, please.

Well definitely some form of error recovery.

Not so necessary, can use PAE for encryption.

Not sure about this. Maybe multiple stand-alone archives based on archive size - but without splitting contents across archives, sort of "best fit to CD/DVD size".

Of course, you omitted self extracting and media file optimisation

[spwolf]

do I always have to do all the work? :-).

So what would Your perfect format have in terms of features Terry?

[Luxor]

In order of preference.

Fast compression.
PDF compression.
PAR-like recovery.
Strong compression.

But I'm easy, I can wait for them all.

[spwolf]

But dont be limited to what I say... JPEG, PNG, GIF, XML, MP3, etc compression?

I am biased towards Backup function so:-
Good loss-less compression
Media file compression (minimally video and picture)
Error Recovery
"Intelligent" Multi-volume
No less than O.S. file size limits on source or archive (quantity or size)
Ability to extract single/multiple files (so no need to extract whole archive as with solid).

Doesn't have to be super fast, but not slower than Zipx maximum at worst.

For general (non-backup) use, then some extras:-
Create Self Extracting archives
Update existing archive (add/freshen)
Strong Encryption

[spwolf]

what about proper versioning, and byte level differential backups, where literally only differences are stored?

[davidsplash]

how about a repair tool for all archivers and sfx files

[Socrates]

My preferences (if doable):
Better PDF compression
Differential backups

[TBGBe]

That only works with good error correction
So version 2.0

well that part is already almost done

read my post david and then read yours... what does repair tool for "all archives" have to do with brand new format in PowerArchiver?

yes, but do not be limited to only things I mentioned... what other things would You want there?

[spwolf]

here is the list of possibles for special compression codecs:

jpg
mp3
pdf/ps
avi
mp4/mpeg/mkv
docx/xlsx/pptx
flv/swf
vob/m2ts/ts
zip
cab
setup.exe/data1.cab
html/htm/xml/py/php/css/js
psd
png
gif
bmp
wav
tar/tar.gz/tgz/tar.bz2
exe/dll/obj/lib
rar
c/cpp/h/hpp/cs/pas
hlp/chm
torrent
msi+B20
mdf
dts
iso


All of these require some special form of compression and each will take a lot of time... so better voice your opinions because if you do not, it might be a lot of time before your "wish" is taken into consideration...

[davidsplash]

in response to my anaswer to my last post what i was trying to say we dont want to see new formats that cannot be repaired. should have made my post clearer but when using android mobile not easy.

[davidsplash]

one format i think we would like to see is sit and sitx decompression.


one i would like to see is .afa
A format that compresses and doubly encrypt the data (AES256 and CAS256) avoiding brute force attacks, also hide files in a AFA file. It has two ways to safeguard data integrity and subsequent repair of the file if has an error (repair with AstroA2P (online) or Astrotite (offline)). The speed of compression / decompression is superior to other systems by making extensive use of multiple processors

one i do like a lot and use is jar the successor to ARJ really good compression rates here

[spwolf]

I dont think David reads our posts too much

Maybe you should open a poll?

Anyway Yes, please -
jpg
avi
mp4/mpeg/mkv
flv/swf
png
gif
bmp
wav
exe/dll/obj/lib

Lower priority -
mp3
pdf/ps
docx/xlsx/pptx
html/htm/xml/py/php/css/js
c/cpp/h/hpp/cs/pas
hlp/chm

Meh -
psd
torrent
mdf
dts
msi+B20
vob/m2ts/ts
iso

Not sure what you mean with these existing formats (conversion?)-
zip
cab
setup.exe/data1.cab
tar/tar.gz/tgz/tar.bz2
rar

[spwolf]

like this?
http://powerarchiver.idea.informer.c...ow=&show_all=1

[TBGBe]

Yes. I like that.
Some of them could do with better description though.

E.G. Just what is meant by <data segmentation and reordering> in terms of a compression format

[spwolf]

i will let eugene explain that... you can also vote, add and comment there!

[spwolf]

one problem there is that anyone can do multiple votes, meaning dont rate everything for the sake of rating, just rates one you feel really passionated about!

[spwolf]

thing was, we didnt want you have to login to vote

[TBGBe]

Err, who is "eugene"?

Note to self - must show spwolf the "Edit" button sometime!

[spwolf]

i hate editing as you wont get email notification with edited parts .

Eugene is our compression engineer, working on actual format (same guy did patchbeam engine, rar speed improvements, wz jpeg decompression, etc).

[davidsplash]

i was just pointing out features in existing formats that would be nice to have included in pa. why right a new format unless you want a format that includes everything.


I apologise its very difficult using android and your forumn nearly impossible

Nice. For some reason I had assumed it was technology bought/licensed from a 3rd party.
