# Thread: Ultra7z Optimizer 0.12 is out

1. ## Ultra7z Optimizer 0.12 is out

Ultra7z Optimizer 0.12

* updated 7-zip 9.20 Final
* now ultra7z.exe uses external 7z.exe and 7z.dll (first from the same folder, then from PATH, then from %programfiles%, then internal) and ultra7zs.exe was deleted.
* added compression modes (you can set -fastest,fast,normal,good,best,ultra,extreme,extrem e2,extreme3)
* added parametres for LZMA, LZMA2 and PPMd ("ultra7z.exe [-best] [-d128m] [-mem1536m] [-fb273] [-o32] [-log] archive_name")
* for parametres "-good" and higher added modes LZMA2 (usually better on already compressed files and EXE) and DELTA (better on BMP and WAV files), "-normal" doesn't use LZMA2 and DELTA for more compatibility whith other archivers.
* at the end it compares whith simple solid lzma and lzma2
* fixed some crashes

2. Hello everyone,

thanks! I announced it here:
https://sourceforge.net/projects/sev...2/index/page/1

Best regards!

3. Hello everyone,

just to let you know:
my AVIRA-AntiVir reports a dropper. Most probably a false-positive?!

Best regards!

4. Try it at virustotal.com

5. I've mailed Avira labs for false positive.

6. Thanks for release!

I can confirm it too. Today I've tried new ultra7z at work and our network version of Avira didn't like it. Well, I included it to exceptions but its defenitly not very pleasant situation.
Here is the report from VirusTotal for original exe:
Original
It gets 16 reactions (40%). I passed ultra7z.exe through latest UPX with some undoc option (which changes the loader) and cleaned the whole UPX signature. Now it gets 5 reactions (12%):
Modified
I can provide you with the modified EXE or the options to use, if you interested.

7. Anyone tried this one yet.

I use this one with Win7 X64, and every file I try gives file not found in 7z.

BTW: nod32 reports no virus

Same for me on XP, SP3, 32-bit. Neither folder-name, nor file-name do contain spaces or dot or other special characters. I tried with two files (one zip and one 7z) in ultra7z's folder and tried batch-files and by hand -> file not found... :-/

Updated AVIRA-signatures do not show alert anymore

Best regards!

The Filename must be entered with full path.
e.g.: "ultra7z.exe [options] D:\fullpath\to\file.7z" or "ultra7z-batch.cmd D:\fullpath\to\file.7z"

Btw, the false positive from some anti-virus is, because Ultra7z extracts the 7z.exe and 7z.dll from it self to %temp% folder, if no regular 7z installation is found or 7z found in the same folder as Ultra7z.

Thanks! Sorry for making noise if I overlooked something.

Either way, the false positive is gone.
Just out of curiosity: why is this done, when 7z.exe and 7z.dll are shipped in the archive => there *is* 7z.exe and 7z.dll in the same folder as ultra7z by default. Double-save?!?

Best regards!

Ultra7z is nothing else as a big batch file. The Ultra7z.exe extracts this batch and work with. When there is no 7z.exe+7z.dll found on some defined folders, the Ultra7z.exe extracts a copy in the folder %localappdata%.
You can try it out yourself, rename all 7z.exe/7z.dll you found on your computer, and ultra7z works anyway. Thats the only reason, why ultra7z.exe is 1,2mb in size

Yes, I do know that. But possibly you want to have a look into the archive one can download via:

the two files (7z.exe + 7z.dll) are shipped inside this archive. So *I* do not see any advantage in shipping a backup for the shipping inside ultra7z.

Best regards!

I think, the author of ultra7z will make sure, that there is at least one copy of a stable 7zip version, V9.20 in this case (lzma2).
