Will past downloads of one’s TW become a memory issue? Can they be deleted? Are they the only access to prior versions of the site?
In my experiance tiddly wikis are 3mb ish or less so it’s going to take a lot of them to fill up that 1Tb hard drive. The download is just an html file, a version of your wiki so as long as you don’t delete the latest one your fine. There is no dependence on previous versions. Of course it’s often use full to be able to go back to a previous save version but that decision of how many/ what to keep ‘just in case’ is entirely yours 
Hope that helps.
Will past downloads of one’s TW become a memory issue?
What do you mean by “memory issue”?
They use up harddisk space. Since the file size starts from 2 up to 6MByte for 1300 content tiddlers as in tiddlywiki.com, they shouldn’t be more of an issue than images taken by a modern smartphone. …
A typical image has 4-6 Mbyte. So if you can deal with your images, you should be able to deal with your wikis 
…
On the other hand it’s easy to compress wikis. On Windows the system can do this in a transparent way.
- A compressed empty.html file uses about 450kByte
- A compressed tiddlywiki.com.html uses about 4.5MByte
Can they be deleted?
Sure as long as you have a backups somewhere if the content is important for you.
Are they the only access to prior versions of the site?
I’m not sure about this question.
Ah, thanks.
How do you deal with past versions/files? Is it easier to make the change in the wiki rather than find a previous file?
What save mechanism are you using? If you are using the default save mechanism, without saving over each change, then there will be a build-up of old TW files in your download folder or wherever you keep them.
There is no versioning system built into TW. So if you want to keep track of changes to your TW files or tiddlers, you’ll have to come up with your own system. There is one or two 3rd party versioning solutions that retain old versions of tiddlers internally.
oh, what are those solutions? and does that mean there are no external solutions? no cloud-based solutions?
There’s more than 20 some save solutions. You can use the navigator application here to explore them.
Re the cloud, there are solutions for saving to github, gitlab, google drive, dropbox, and also special TW sites like TiddlyHost . You could, in theory, also host over you own web or webdav server, though doing that safely on the open internet is another issue.
Look for the various backup solutions as well. I use Timimi Browser and Host addon so I just edit files and the backups can be automatic. I also use TiddlyServer and just purge (delete) older backups occasionally. I think just using a tiddlywiki single file on drop box ends up with dropbox versions.
Basically whole of wiki backups are trivial but related to the saving mechaisium you are using. Solutions such as noteself do retain tiddler versions by design but you need to provide the database infrastructure.
Personally I have thought of building a method to store just a few tiddler versions in the wiki, perhaps using a mechaisium similar to Mohammad’s Trash Plugin, perhaps only retain versions for a limited period. But then you can also build an archive mechaisium within or outside your wiki for critical document (large) tiddler content.
I’m not understanding all the way. Are
Timimi Browser, Host addon, and TiddlyServer free external automatic storage plug-ins? If so, how can I find video tutorials? On TiddlyServer, for example, the instructions go over my head.

I would first just play with tiddlywiki and click save to save your changes locally. Next time open the file from your hard drive and download again and save over the last one.
Once you have become a little more familiar look for instructions on tiddlywiki.com on using the different savers. Once you know a little more it will be easier for us to start, come back and ask for support again, giving all the information you can eg Browser, Operating System what you are trying to do and where you get lost or it goes wrong.
