PA can't extract; XXX does…#2

I’m using the latest version of PA: 9.10.06

download this file:
http://www.mlin.net/files/Clipomatic20.zip [96KB]

then uncompress it, you’ll have another file named Clipomatic.EXE [111KB]; it’s a self-extracting ZIP archive.

try to extract it with PowerArchiver…it will fail: “Error reading ZIP file” :(
use WinR**, it will extract it smoothly…

what’s the problem, this time?
check and fix it, mates! :)

Hi,

this file is badly created ZIP SFX, and is out of spec. As discussed before, zip engine (dynazip) hates zip files with bad headers.

Zip repair tool works fine on this file and will help you to recreate an proper zip archive out of it!

thanks,

[manuangi]

got that.

let me say that the normal user, who doesn’t come to this forum nor knows of its existence…how can he imagine about the bad header-thing?

he will just see that WinR** works, PA does not…

I hope there are few other things that PA does and other dont :-).

We cant do anything with badly created zip archives except provide the tool that fixes them and we do and it does, so it works :-).

thanks and have happy holidays!

I think I have a good idea: I could not think about trying to correct the zip file via the proper tool of PA…why don’t you create a visual hint for that?

for example, when the error win pops up, it could go “error reading zip file. try correcting it via the Repair Archive tool” (something like that)

what do you think?

[spwolf]

Good idea.

@spwolf:

Good idea.

I’m happy you like it! :)

btw, I have updated to 9.11.01…and now PA correctly extracts the file! so…how’s that, if you changed nothing about the handling of bad headers?

The ZIP repairing tool works good BUT… you’ll first have to rename Clipomatic.EXE to clipomatic.zip for it to work on the file.

In fact, the ZIP repairing tool doesn’t allow you to choose anything else than ZIP files.

It would be good if it could directly get exe sfx files as well…what do you think?

(I think I’m going to put it in the wishlist as well…)

You just enter . into the filename field and it will show you all the files in that folder, if you select that SFX archive, it will “fix it” even if it is an EXE.

Problem with putting general “*.exe” in there is that, obviously, it would show both SFX archives and all other EXE files. While you might know the difference, an average user might not :-).

right, but the average user would never guess to put the . to be shown all files…I guess I’m more than an average user, but I couldn’t think of that simple trick! the normal user should be assisted in the largest way, I believe…

and don’t forget that the tool’s named “Zip repair”…so one can’t promptly guess that it can be useful also with exe sfx archives…
