#1086 'Extract to "*\"' extracts all archives to same directory

After selecting multiple CABARC-based self-extracting archives (eg: Visual C++ 2005/2008 runtimes) in Explorer, use the context menu command 'Extract to "*\"' causes the contents of both archives to be extracted to the same directory, instead of separate directories. The bug does not occur when at least 1 archive is not CABARC-based self-extracting archives, including self-extracting CAB archives created by InstallShield.

In addition, extracing multiple self-extracting archives causes the output directory name not matching name of archive. This bug also occur in occasions when self-extracting archives are not CABARC-based. In the case of CABARC-based archives, all files are extracted to CABINET~ directory.

There is no simple way to fix it now. 7-Zip uses file name of internal archives inside .exe. And these names are same.

How about just treat the internal name as folder, or simply ignore it altogether?

This bug was not present in 4.65. I don't see how there is no simple way to fix it.

I don’t understand the problem. Why would you bother handling SFX archives different from any other archive format?

If you select multiple .7z, .zip, .rar, etc. files and select Extract To \*, it creates folders for each, using the filename of the archives. This is the behavior that users would expect.

Why then can it not simply do the exact same thing for SFX archives? For example, if you select foobar.exe and baz.exe, then selecting Extract To \* should create the folders foobar and baz to extract them to.

Over 4 years later and this still is an issue!
I often have to extract several files. For instance today: 13 driver files for an HP notebook. I select them all, rmb-drag and select 'extract to "*\"' and 7zip ends up extracting all files to the folder '[0]~', creating one big mess of files.

It's already fixed in latest alpha versions.

Great, thanks!
Edit: just tried it with 9.34 and it works as expected. TY!
