Tried to load HD 4.7.1b in GZDOOM builder.

All hideous destructor versions I tried broke GZDoomBuilder. Please help!

Unable to load resources from location "C:\Users\Bennett\Downloads\hd-4.5.0a.pk7". Please make sure the location is accessible and not in use by another program. The resources will now be loaded with this location excluded. You may reload the resources to try again.
NotSupportedException when creating data reader: Specified method is not supported.

UDB likely does not know how to handle a .pk7 file (which is a renamed .7z archive). Try extracting the .pk7's contents into a separate folder (you will need 7-Zip), and then use that folder as your resource package.

Sure post away.
However, there is no need for this if you followed wildweasel's instructions.

Just to repeat said instructions:
Use 7-zip to decompress hd-4.7.1b.pk7 into a dedicated folder.
Then load this folder as resource in UDB, for example

Spoiler:

You'll get a litany of errors and warnings, which can be mostly ignored

Spoiler:

And you are good to go.

To confirm, UDB does not support the compression methods in a 7z file. It's fine with zip files ("pk3") but not 7z ("pk7") files.

Personally, it is also my impression that GZDoom takes slightly longer to decompress pk7s compared to pk3s. So, even though pk7s tend to be slightly smaller, I feel that pk3s are a better option (UDB support plus faster loading in GZDoom and support for the format in almost any file archive handling program, including Windows explorer).

decompressing 7z takes indeed longer - that's because solid 7z archives require decompressing data from multiple files to get the one you want. Generally it's not really advisable to use 7z for content distribution - I really don't understand why HD has to go the inconvenient route here.

Thanks for confirming and explaining.

Out of interest, would there be any value in using 0 compression even in a pk3/zip?

My guess is that it might make initial loading slightly (barely noticeably) quicker but after that, unless resources are decompressed on the fly as they are needed (I don't think they are?), it wouldn't make any difference.

Actually, decompression time can even be less than the overhead from reading more data from a file.
