New Mod Detection for mods already downloaded

[lavenderbeard]

This is just an idea because I do not have a strong background in computer science, but I hope the devs will look at this and consider implementing.

 

There needs to be a way, perhaps through SHA-1, MD5 or another encryption mechanism that will allow the vortex to detect mods that have been downloaded from other sources, such as manually installed, or from steam workshop or another mod manager.

 

I hope it is a planned or on the to-do list

Mods downloaded from Nexus Mods are identified by the MD5 hash of the zip archive that is downloaded. If you download from other sources you'll need to make a custom extension to support identifying them.

That might explain the problem I had recently with a mod from afkmods; everytime I installed it Vortex insisited on identifying it as a Nexus mod (in Italian no less!). I renamed the archive and Vortex stopped doing it, the problem was not actually the identification details, they can be manually edited, but the image that Vortex shows when you double click the mod, that doesn't seem to be deleteable:)

renaming the file shouldn't have any effect, that's pretty much the point of using an md5 hash.

 

If you add a file to Vortex through the site (from a "Download with Manager") button then Vortex can already identify the file based on Nexus Mods specific ids. But when you add files in any other ways, either by downloading from Nexus Mods manually or a third party site, _then_ we generate an md5 hash and, together with the file size query if Nexus Mods knows that file.

So even if you got the file from a third party site, if the file was _also_ uploaded to our site it should be identified. Since we use hash + size it's practically impossible we would identify the file incorrectly but it is possible that users re-uploaded other peoples files, potentially with incorrect or localized descriptions.

Is the hash plus file size used to populate the rh side bar with the image (above 'archive name') at its top?

Indirectly, yes. If the md5+size lookup gives a result, Vortex knows which file this is on nexusmods.com and then it can use the API to fetch additional detail like the description and image and everything.

But if the file was downloaded from nexus directly (through the "Download with Manager" link) then we don't need the lookup so fetching that data is one step instead of two.

[dizietemblesssma]

Then based on just the one incident of collision that I experiended with a non-nexus mod:) can I ask that Vortex allow to delete/alter the image that it fetches?
