PA cannot compress file in use?
-
Sorry that I don’t know if this issue has been held or not… Currently I wanna compress a MP3 album folder and PA compress all files perfectly EXCEPT the file is being played by Winamp. I’ve checked the “Configuration” and didn’t find any option to solve this. Using WinRAR as a comparison, it works without any problem. Is there any method to overcome this issue? :confused:
-
NO, PA doesn’t support this feature.
But I hope it will support it in the future
-
I also hope PA would support this, too… The file in-use should only be locked for “writing” and “appending”. I think this function could be implemented with not much effort.

Hi,
If you use 7zip format, it will work just fine.
thanks,
-
it should work for all formats ;)
-
Yes, but I usually use ZIP for archiving due to the efficiency. So, if 7-Zip format works in this way, why not ZIP? ;)
-
the reason is simple zip has to be compatible with other zip programs and changing the zip format will take time its not that pa can’t do this its just that way boither when a better format 7-zip which is still being developed with no restrictions on what the format can do. Zip is not really being developed and to chage it would make it uncompatible with all the zip programs around. Unless you can pursuade the big archive gives to support this new zip format.

davidsplash,
What format would be changed? I don’t mean ZIP has to become 7-Zip. I just ask if PA can compress file in-use when using 7-Zip profile, why don’t PA compress file in-use when ZIP profile is used?
Would there be any misunderstanding made?(Supp. information: In my first post, I do mean WinRAR can archive files which are in-use using ZIP profile but not RAR. Therefore, ZIP file format and structure won’t be changed even ZIPPing files in-used.)

I understand what Ricco means.
Sometimes I like to compress a little program in use that I’m developing and send it to a FTP location.
PA didn’t compress it using zip profile.
So I had to use 7-zip to do the job with the same file type: zip.
This limitation of PA’s zip is really annoying…

because our zip engine does not support it, and it wont support it anytime soon due to possibility of your files not getting archived properly when in use.
It is an limitation of zip engine that we use. If it bugs you, I suggest that you use 7zip format. It is fast on lower compression methods…

Thanks for your notification! But I still hope it could be solved earlier. :)

but WinRAR DOES support this feature :rolleyes:

Then you should upgrade you ZIP engine as soon as possible. Didn’t you say that you always use the best components available on the market? Nearly every compression program can skip files in use.
-
Or even, if source is provided, update the source of the ZIP engine would be a faster approach.
-
What about the Command line PACOMP? Are files in use being skipped there as well?

there is no better than what we use… It is simply an limitation of current PA zip support, it can not be “fixed” or added quickly.
I can only suggest that you use 7zip format if you run into these kind of problems.

I have a suggestion. You may consider it as “Wish List” instead of Support…
I suggest that PA should develop a ZIP engine instead of relying on third-party components. It’s quite hard to develop from something raw and therefore I think it’s not bad to purchase the source of the ZIP engine which is now used by PA. Afterward, PA can amend the source and add any new feature (such as ZIP-ing file in-use) without waiting the third party.
-
a warning should be issuesed when files in use.
However i tested winrar and it does do what you say though it looses a bit on zip compression doing so. pa has better compression on zip than any other zip proigram. why not use 7zip instaed for this type of work. as I said before zip was not designed to be used like that. 7zip was.
-

This has nothing to do with the target archive file formats - it only has to do with how the component that is opening the file to be compressed makes the file open request to Windows.
-
It should be better if you make your Vote for this feature request in the Wish forum ;)

hm, can anyone tell my how to change from zip to 7zip if i use backup express. i can only choose zip, lha etc. but not 7zip?

You cannot use 7z within PA BAckup Express (yet).
-
i see - then it’s very confusing that someone recommends to use 7zip format to support compressing locked files. so i can’t use 7zip in backup and also locked files are not supported (because i can’t switch from zip to 7zip in backup mode). right?
-
Well yes, but Backup Express is “normally” used for archiving (e.g. overnight). So then files are not in use.
As requested by Ricco - the advice to use 7z was for compression tasks using PA or shell extensions, such as compressing MP3 file whilst it is being played.
For Backup Express, you could use TAR.GZ, TAR.Bz2 or even BlakHole compression. These do allow working with “files in use”.
Also the compression will “probably” still be better than ZIP format - but not 7zip (of course this depends on what is being compressed). -
ok, tar.gzip worked. thanks!

Hi guys, I also complained about this a long time ago and with the new update v9.63.02 found that some of the files in use are added to ZIP correctly when highlighted and Right Mouse button-> Compress with Options is performed :)
However some files are skipped when using the Drag-and-drop in PA or using the PA graphical user interface to Add to a new archive :confused:
What is the difference ?

there shouldnt be any difference, it was never added.
