    • ZIPX: Add support for packing JPEG with specialized algorithm

      A

      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!

    • Better archive type handling with drag & drop

      BigMike

      Hi,

      I’d like to suggest, that the correct archive type is (always) selected, when adding files by drag & drop to an archive.

      This is already happening if the archive has the correct extension. For example, if I’m adding files to test.zip, zip will be selected. If I’m adding files to test.7z, 7z will be selected as format in “Add dialog”.

      But this won’t be working, if the archive has not the “right” extension.
      So XPI files (Firefox addons) for example are ZIP files. PowerArchiver opens them without any problems, but if I try to add file by drag & drop, PowerArchiver won’t auto select “ZIP”, but use the last selected archive format, while PowerArchiver already knows, that I’m trying to add files to a ZIP.

    • Elevation of UAC in Mounting Images

      F

      I love this, only there is one problem. The UAC elevation feature does not extend to Mount Image option in the add-on software PA provided. It is most annoying whenever I am on highest UAC settings and I mount an ISO, every time I open and create a virtual drive UAC appears. I also do not want to completely disable UAC.

      Is adding UAC elevation for mount image feature possible?

    • Bulkzip Nanozip (.nz) file format

      The now defunct Bulkzip had Nanozip (nz) as an option this would be great to have for compatibility with my .nz files, so I don’t have to install Bulkzip separately.

    • Include Virtual Drive as standalone in the installer

      2

      Hi.

      I noticed that when I want to run the Virtual Drive for the first time inside the PowerArchiver Burner it prompts to download it form the internet.

      I was wondering, would it be OK to include this utility straight into the offline installer to be able to set it up locally?

      Thank you!

    • Suggestion to improve .pa format

      Brian Gregory

      How about recognising a few more (or all) of the file formats that are basically renamed zip files and treating them is if they are zip files.
      For instance Android .apk files are just renamed .zip files.
      Libreoffice/Openoffice ODF documents are all, as far as I am aware, just renamed .zip files. (.odt, .ott, .ods, .ots, .odp, .otp, .odb, .odf etc.)

      I would like to make a further plea for my mouse’s backwards and forwards keys to work when navigating to and from files, just like they do in explorer. IIRC, I was told that this functionality would be added to v2019.

      Mni tnx.

    • Quake 1/2 .PAK file support

      I use PA for everything, if I can.
      Would be really nice to maybe get built in support for Quake 1/2 .pak files.
      More info on the format, seems simpler than I thought: https://quakewiki.org/wiki/.pak

    • Find file in archive.

      Luxor

      Would it be possible at all in some future version perhaps, to have a “find file” function?
      Reason I ask is that I was looking for a certain file I knew existed in an archive, but I had to unzip it then use another tool to find the file. It would have saved that extra step if that function existed in PA itself.

    • Encrypt files inside archive that has already been created [.zipx]

      2

      Hi.

      Is there a way to enable the user to encrypt the files inside a ZIPX archive that has already been created?

      This could save time for large archives that the user may need to encrypt at a later stage or that he/she has forgotten to enable encryption before creating the archive,

      Thank you!

    • Fast Extract large files directly to target directory

      2

      Hi.

      I would like to see a new feature implemented: a ‘Fast Extract’ Mode.

      Currently PowerArchiver extracts files to a temporary directory and then moves them to the target directory chosen by the user. At least via drag and drop.

      This can be both time consuming and needs free space on the system drive for large files.

      Is there a way to directly extract files to the target directory with PowerArchiver?
      And if not, can a feature like this be considered for future updates?

      Thanks very much!

    • Serpent-256 Encryption for PAE/PAE2

      2

      Hello.

      I believe it would be useful to implement Serpent-256 encryption for PAE/PAE2 formats, even though PowerArchiver offers strong encryption ciphers already.

      (deleted part advertising other software - admin)

      Do you think this will be a useful addition?

      Thank you for the consideration!

    • Make portable version compatible with PortableApps

      A

      Hello!
      I think it would be a great option to make the portable version of PowerArchiver compatible with PortableApps (i.e. adding the necessary files and folders to integrate it smoothly into their structure).
      I own various other commercial programmes which -when installed in portable mode- offer to make the becessary changes without needing an extra installer or the official PortableApps repos.
      Thanks for opinions or perhaps even a realization of this.

    • I think SVG files should be treated as text files.

      SVG files (scalable vector graphics) seem to be special XML files and therefore when added to .pa archives I think they should be compressed as if they were text files.

    • Command Line Switch for View Mode

      BigMike

      Hi,

      I had a look at the command line switches, but there are no switches to change the startup mode.

      At the moment, PowerArchiver opens in the last used mode.
      I’d like to have command line switches to influence the startup mode.
      Basically, the aim is:

      Opening PowerArchiver from Start Menu or Desktop: Start in Explorer Mode Opening PowerArchiver by double clicking an archive: Start PowerArchiver in Archive Mode

      I know CRC32 was the standard for checking the integrity of compressed files but it is not really used anymore. Can you add ones that are used now MD5 or SHA?

        @bigdog I think It’s just showing you the value from the directory in the archive. If you stored a MD5 or SHA1 there instead of a CRC32 you’d have a new archive format that nothing else would understand.
        I guess they could have used them on their own new PA format. But it’s too late for that now. PA2 or PAX anyone?

        Indeed, what is used for data check is defined by the format. So using anything outside format specs would make it unreadable by everyone else.

        But main reason CRC is used is because it is faster and has same function for this purpose as MD5 or SHA, so using something else would just be slower and would create larger archives - it would make no sense.

        However this is only true for data check in archives. When using encryption, we use SHA2… or for instance in PA format for data deduplication, a variant of MD5 is used.

        So everything has its purpose.

        In 2017 we sped up zip compression by adding faster cpu/hardware optimized crc algorithm that uses cpu instructions, together with some other optimization this made zip compression of large files significantly faster than before (even up to 2x).

        thanks for the feedback!

            In the window that shows the files in an archive where you have a column for CRC, that could be re-purposed for those newer hash codes.

                  I assumed (maybe incorrectly?) that those hash values were being calculated in real time when opening (or verifying) the archive. If that was the case it should not matter if that is not the standard from the days of old as the program is just displaying additional data.

                  Thanks
