Can you include .3MF to the list of re-compressible formats? Its structure is similar to MS Office 2007 documents and Open Document Format. It is a ZIP Deflate archive with XML data and some JPG, and/or PNG pictures inside. Otherwise, if I try to compress .3MF it bearly makes it smaller unless I recompress .3MF to the Store setting then it makes it a lot smaller.
Wish they all would move to 7zip ZSTD in the first place so that the optimized file size with FileOptimizer would be 50% of the ZIP Deflate version. And there would be no extra compression needed :)
I noticed that the option to add the optimize archive function to the context menu is missing on Windows 10.
Opening each archive with the interface in order to click it becomes tedious with many files.
Same for others functions like Remove Archive Encryption
ZIPX: Add support for packing JPEG with specialized algorithm
-
Hello!
I know I have been asking for this feature some time ago, but as nothing has changed let me ask again:
The ZIPX-format offers an algorithm, that compresses JPEG-files by about 20-30%. Please add compression (packing) support for this in ZIPX-archives to Powerarchiver. Extraction of JPEGs packed into ZIPX by this algorithm is already supported by Powerarchiver for a long time, so it should not be difficult? Or is it a licensing problem?
Thanks! -
Good evening,
I am also in favor of implementing the decoder for JPG files in Zipx format, because this would really increase the compression ratio! The best would be that for as many file types as possible, the appropriate decoders would be implemented. Also Precomp would be another idea, the decoders and Precomp should be usable in .pa format as well as Zipx format, that would be great! You should team up with the guys from Encode, the guys are fit, what compression algorithms are concerned, I don’t want to mention any competing products, but there are programs, which with the right settings and the corresponding decoders and Precomp, achieve much better compression rates than Powerarchiver or your . zipx format, also I am disappointed with Powerarchiver and if after my 3 year Toolbox license nothing improves (especially what all the bugs in the program concern, PowerArchiver is there for over 15 years and “feels” extremely unfinished and after alpha or beta), I will not renew the license and look for alternatives (Which are often even free). -
I would be perfectly happy, if PowerArchiver offered me a portable solution with FULL (i.e. also compression and not only decompression) support of all methods offered by ZIPX.
Once again: as unpacking is already implemented for all ZIPX-methods it should be possible to also add packing?! Or is it really a licensing (WinZIP patents) or marketing (further pushing PA-format) issue?
While I think it’s good to develop and push an own technologically advanced format like PA, there is also a need for compatibility, interoperability and exchange with others (using other software) . And ZIPX is currently more common because of the great old name and the wiedspread use of its originating software, WinZIP.
