Somehow I expected that when I installed the SE Software I should get a .sis windows shell extension that told me information about a .sis file in the PC!
I mean, right-click in a file -> click Properties -> Version tab.
It would be very nice to see stuff like Name, Company and Version!
Any programmers out there willing to take the chalenge?

If anyone knows the .sis file binary format, please post here.
I think with a bit of help I can develop a windows shell extension.
Something like this:

BTW, this shell extension is very usefull to check if two files exactly the same size are *exactly* the same.

@ph03n!x

1. It's wrong to assume the size of a file increases with each version.
2. Everytime you download a .SIS from the web, the file gets the date+time of the download, not of the actual build.

The .sis format isn't exactly documented in any way thats accessible if you're not a symbian premium partner, but its an old format so it has been more or less reverse-engineered.

I wrote a quick test-extractor a while ago based on this information:
http://bowman.rtfm.se/sis.html

I never finished it, but it does work for some files (for others it will likely just crash).

Source here (win32 cmdline app, pascal):

Thanks for your link, but I've already found that page.
I don't know how much time I can dedicate to this, but I'm guessing that by the end of next week I will have a Windows-Explorer-Shell-Extension-Property-Page (lol what a name) that shows all the information about a .SIS file.
I'm creating the property page right now. The extractin of the info should be the easy part! (just read bytes and interpret them)

In the second version I will make possible to *change* the data in a sis file. At your own risk!

Of course I will make it available (with source) anyone that wants it.
