F.A.Q.

1. Is ZipGenius free?

Yes, ZipGenius is totally free and you don't have to pay to download and/or use it. If someone has asked your money to use ZipGenius, let us know!

2. Can I use ZipGenius in my office or in my company?

Surely! ZipGenius can be used freely in any environment (office, company, organization, association, school, home, etc.) and it can be installed on an unlimited number of workstations.

3. How many formats does it support?

Check this page and you'll find how many.

4. Can I create RAR archives?

No. WinRAR® developers didn't release the compression library to third parties.

5. I would like to distribute ZipGenius in a cover-mount CD for my magazine: do I need an authorization?

Just write an e-mail (english or itailan) to this address.

6. My antivirus is telling me that ZipGenius DLL files are infected with a trojan. What should I do?

99% that is a false positive from your antivirus that has been caused by the UPX compression used to shrink the DLL files you see. Those DLL files, however, don't contain any kind of software code because those are just resources libraries. Please, report the false positive to your antivirus software publisher and get an update for the virus database.

7. I tried to compress MP3/MPEG/AVI/JPEG/PNG files but they don't get smaller. Why? Is ZipGenius working correctly?

That is not a ZipGenius problem. Those files (and many other) are already compressed upon creation, just like MP3 or DivX files. If you try to compress further these files you could get two opposite effects: they could shrink just about 0.5% of original size or they could even get bigger.
By default, ZipGenius avoid to compress these files, unlesse you select the BRUTAL compression level.
If you need better compression, you could try with the 7-zip format (.7z extension), which offers very high compression ratio.

8. What is UPX? How do I use it in ZipGenius?

UPX is a great compression software for executable files like .EXE, .OCX and .DLL. UPX is an open source project available at http://upx.sourceforge.net. In ZipGenius recente distributions, UPX has been included in order to add a new compression level named Brutal+UPX. This is the highest compresson level provieded by ZipGenius. If you want to enable it, you can download upx.exe and copy it to ZipGenius program folder; ZipGenius will detect it and you will get automatically the new compression level.
By selecting Brutal+UPX, ZipGenius will create a list of files candidate to beprecompressed through UPX; you will choose UPX compression level and ZipGenius will precompress (if possible) those files, then it will go on with the normal compression routine.. If you want to learn more about the advantges of UPX precompression, read this PDF document.

9. I would like to uninstall ZipGenius but I get the message "File unins000.dat not found": what should I do?

This happens when you use an uninstaller program to remove "useless" files from your system: it could delete files "useful" to uninstall programs. Please, remove Windows application from Control Panel!
Fix this issue following these steps:
  1. Click Start > Run and type:
    regsvr32 "C:\Program FilesZipGenius 6\contmenu.dll" /U
  2. Download this file and decompress it on your desktop.
  3. Reboot your PC.
  4. Manually delete the folder "C:\Program Files\ZipGenius 6"
  5. Double click on the .reg files you will find, following the order represented by their filenames ("Step 1" - "Step 2")

10. Does ZipGenius run in Linux?

You could use WINE to run ZipGenius with limited functionality and with stability issues.

No, but we are searching volunteers to develop a Mac Os version. If you are interested, contact us.
