i see that i have some issues with SLADE when i try to open a pk3/wad file like this:
Spoiler: Image 4 You (Open)
there is a way?

I'm not sure of the cause, but you can open PK3s using 7zip if you absolutely need to.

Hallo,
It could be that the archive data file is compressed using something other than the Deflate algorithm. If this is the case, most programs using various libraries (gtk, for example) well not handle well. In other words, the issue is not fixable, unless the specific libraries are updated to support various compression algorithms (LZMA, PPmD, for example) or use a different library if possible.
Because pk[3|7] are essentially archive data files, just open the files using 7zip, as mentioned by Marcaek.

Thanks for that guide too as i thank Marcaek.

Maybe if you open the pk3 in 7zip and save it (Save-As to a different name, to be safe), the file will then open in Slade.

Hallo,
If you want to go that route, it would be best to re-compress the contents with a different compression algorithm that SLADE can properly support (most likely Deflate). Though, you are not really saving anything, but recompacting the data with a different algorithm.

That's what I was getting at. You are saying that simply saving it again wouldn't do that?
