Option to enable compression of open files
I would like to compress log files, which are in use by the corresponding application. Unfortunately this is not possible with PowerArchiver, but with WinZip (gives a warning).
Could be interesting also for files, which are known to be open for reading only.
you can do so with 7zip format, but not with zip, inside PA.
So if you select 7zip, you will be able to compress files in use…
Thanks for your help!
My version of PA is 10.01.03 - with that version it does not work.
Why is it not working with zip? I thought internally the compressor simply gets something like a Stream of bytes to compress.
it will work with 7zip, unless files are exclusivly in use (not just being accessed) in which case it will not work (and it is not possible for it to work).
It doesnt work with zip at all, since zip engine checks file open handle and simply doesnt even try to compress files which have file open handle.
Bam! Wish granted. Please look at PA 2009 Beta 1.

How is this being done? Did you just swizzle your CreateFile parameters or did you go all the way and use VSS?
it opens shared files but not files exclusivly in use, such as with VSS (yet)… it is being planned, but there are other things currently on higher priority.
