RSS reader - deleting opml files

While I haven't used g2reader.com, my experience with OPML has been that when I import the files, it adds the lists to my subscriptions.  There isn't a "remove" as it basically does a one-time merge of the feeds in the file with your subscriptions.

How do I get rid of them?
Everyday, I get hundreds of feeds.  How do I stop that?

I think each one has to be removed individually.  This would be a good question for g2reader.com support as you are asking about specific functionality of their product.

I have emailed them 3 or 4 times, no response, they are worthless.  It's been 3 weeks already, and no response.

I just looked at their site, and it looks like it is a pretty small development team there.

Personally I have been using Feedly.  This lets me put feeds into groups.  When I delete a group, it will remove all the feeds in that group.  Feedly doesn't have a way to undo a OPML import.

So if I were to use Feedly, there's no way to delete the imported opml files either?

So what if I make a change to my opml file, don't I need to delete my current one and import the new one?

Actually, I don't care what website it is, do you know of any that are: 1. free, 2. that supports opml files (to add/delete them)?

Feedly is free.  They let you import and export OPML files.  When you do an import/re-import of an OPML, it will take the feeds in the OPML and add them to your subscription list.  It doesn't flag them as part of the OPML, so you can't delete it to remove those feeds.  It does let you put feeds into groups and when you delete a group it will remove all the feeds in that group.

If you import an OPML that has already been imported, it will only import the changes and will not subscribe you to the same feed twice.

OK, but how do I stop my feeds from an opml file, so how do I remove an opml file?

For example, I have an opml file for craigslist, for every city in the U.S, it's over hundred cities I believe, as I'm looking for something rare.

I made some changes to the search term, so I need to import a new opml file, or if I deleted a lot of the cities and now only want to search in 3 or 4 cities, if it only imports my changes, then it will also keep my old feeds, so there's no way to actually delete the old opml file?

The old feeds would have to manually be deleted.  There is no way to delete feeds based on an OPML file.

ok, I created a feedly account and after importing my feeds, there's over 300.
How do I delete them all?

Along the left bar there is an option to Organize.  This will list the groups your feeds are in.  You can use the X to delete an individual feed or when you hover over the name of a group, there will be an X to delete the entire group.

I don't think they are in a group.  So how do I add all of them in a group?

so it didn't group anything for me, I just need to get rid of all these feeds now, as there's hundreds of them.

Thanks for your help
