Small issues with archive integrity.
in Site Issues
After finding out another item removed because of DMCA I've decided to make a private copy of WinworldPC collection.
Took some time (few months), but it's finished now and as I have found out winworldpc.com is surprisingly small (at least files that you can download): slightly more than 8000 files, around 550GB total size. I kinda always assumed it would be much bigger.
For the future reference I have created ls-lR, md5, sha1 and sha512 files (attached).
Most files have verified fine, but there are few where checksums don't make any sense or don't match the content.
Download f8d2d0a4-031d-11ee-8470-0200008a0da4 “Textra 3.1 (1985) (5.25-360k)” has checksum from different download: 9753c54c-031e-11ee-8470-0200008a0da4 “Softerm Classic for DOS (1993) (3.5-1.44mb)”
Downloads 864df503-855b-11e9-ab10-fa163e9022f0 and d6bba27c-8556-11e9-ab10-fa163e9022f0 (both named “Palantir WinText and WinTime Demo (6-13-1988) (5.25-1.2mb)”) have the same checksum and send you to the exact same file on the download server… but only d6bba27c download actually succeeds! Probably limitation of a download system?
Download 6216a8f0-fd77-11ed-aca0-0200008a0da4 “myHouse 1.11 for DOS (1993) (5.25-1.2mb)” couldn't be downloaded at all (but has links!) while downloads 76cd168c-5f06-11eb-b764-0200008a0da4 “OpenVMS 8.4 Hobbyist Kit” and e35dac03-5f02-11eb-b764-0200008a0da4 “OS/400 V4R4” don't have any download links (yet, somehow, have a checksums? weird).
Really strange (and somewhat funny) situation is with download 41c38b75-c3aa-7d0f-11c3-a7c29d255254 “Borland Delphi 3.0 Standard (ISO)”: for some crazy reason this download has incorrect checksum… yet I have file downloaded years ago which have the exact same checksum as specified on the web site! Both files are valid archives, with the exact same size (254,743,859 bytes precisely!) and content… yet packaged form is wildly different… what kind of magic is that? Someone unpacked file and then packed it back? Why?

All archives look fine, they can be downloaded, just checksums don't match. In some cases it's obvious that checksum is a nonsense (e.g. 4152e167-19dc-11ea-9911-fa163e9022f0 “WordPerfect 4.1c (1985) (5.25-360k).7z” have, literally, “WordPerfect 4.1c (1985) (5.25-360k).7z” in place of checksum), in many cases it's not clear if what's there is just part of checksum or maybe it's some exotic checksum…
But the majority of files in the archive match with checksums from the “download” links.
And an additional issue that is strange: for some reason some german versions of Internet Explorer are duplicated. Archives have the exact same names, but 3dc2a7c2-bbc3-8618-c39a-11c3a4e284a2, 3dc2ae15-c385-18c3-9a11-c3a4e284a2ef, 3dc2af5b-4818-c39a-11c3-a4e284a2c3a5, 3dc2b5c2-b7c2-a918-c39a-11c3a4e284a2, 3dc2bc11-c384-18c3-9a11-c3a4e284a2ef, 3dc2bd58-7918-c39a-11c3-a4e284a2c3a5, 3dc383c2-b537-18c3-9a11-c3a4e284a2ef, 3dcb9c76-c3ab-18c3-9a11-c3a4e284a2ef are in the “Beta Applications/PC” while 3d3e2c54-18c3-9a11-c3a4-e284a2c3a570, 3d40c2b6-c2a3-18c3-9a11-c3a4e284a2ef, 3d41c3bb-c3bd-18c3-9a11-c3a4e284a2ef, 3d43414f-18c3-9a11-c3a4-e284a2c3a570, 3d45c38f-1a18-c39a-11c3-a4e284a2c3a5, 3d47140f-18c3-9a11-c3a4-e284a2c3a570, 3d4859c2-b518-c39a-11c3-a4e284a2c3a5, 3d49c29d-c3b9-18c3-9a11-c3a4e284a2ef are in the “Beta Applications/PC (International)”.

They have the exact same content, except for different disclaimer (winworldpc.com.txt file)..

Checksums were more important back when the mirrors were using plain HTTP. They are HTTPS now, so less issue of corruption in transit.
I'll look in to those whenever I can find some time.
And yes, it's obvious some files were changed over years… but some changes are… really strange for me.
E.g. “Microsoft FORTRAN Optimizing Compiler 4.1 (5.25).7z” file downloaded long ago… today it's download 4863c2bf-c2a5-18c3-9a11-c3a4e284a2ef that gives you file “Microsoft FORTRAN Optomizing Compiler 4.1 (5.25).7z”… but why anyone would want to take correct name and change it to incorrect one?
Note that the "download" name on the page and actual file name may differ.
