Deleting Multiple Tags?
I just imported several folders to Zotero and it imported all kinds of weird tags (even though I had this option unchecked). Even after I clicked "Delete Automatic Tags in this Library" there were still thousands of tags left. Is there a way to mass-delete these? I don't want any of them and would prefer to start from scratch with my own.
The Zutilo plugin can remove all tags from selected items. (A future version of Zotero will include that capability as a built-in feature.)
It is not clear how best to delete multiple tags in bulk/batches.
1. Install Zutilo
2. Assuming that the tags you'd like to keep are not in their hundreds, select each tag you'd like to keep, and move all the items with that tag into a new collection, named after your tag. Repeat for each tag you'd like to keep.
3. Use Zutilo to delete all tags from your library
4. In each of your new collections select all the items and assign a new tag named after that collection. Since items can be multiple collections, they will also receive multiple tags.
5. Delete the new collections you created in step 2.
6. Problem solved!
1. If you have tags you want to keep, create a new collection (e.g. I named mine 'Saving coloured tags' < create a new folder for each tag you want to keep < copy all references with that tag into their specific folder.
2. Install the Zutilo plugin; https://github.com/wshanks/Zutilo (full installation instructions are on the webpage if you scroll down)
3. As is_PengLu has said at https://forums.zotero.org/discussion/comment/406821#Comment_406821 , "After installation of Zutilo, go to Tools < Zutilo Preference < User Interface < Remove tags [second option down] --> deselect 'hide' and select 'Zutilo context menu' so that 'Remove tags' will display when you right click an item
4. OPTIONAL: on the zutilo preferences menu (Tools < Zutilo preferences) click on the 'Shortcuts' tab on the top, scroll down to find 'Remove tags', select it, and enter a keyboard shortcut (I did Shift+R): this will enable you to remove all tags for the selected item(s) by pressing Shift+R
5. Go back to the main zotero window and select 'My Library' (Brown folder). Click Command+A to select all items, then Shift+R (or right click < Zutilo < Remove all tags) to remove all tags in your library
6. Reinstate the tags you saved by going back to that new collection you made in step 1 ('saving coloured tags') and add back the tags to each reference in those subfolders. You can quickly add the same tag back to a list of items by draging a set of items to a tag in the tag selector on the left (as per https://forums.zotero.org/discussion/64065/tagging-multiple-items-at-once)
This seems to have worked for me at removing the hundreds of useless tags imported from EndNote and has synced across my desktop and laptop fine. Hope that helps!
1. Mark all entries in the library or in a collection, contextmenu -> zutilo -> copy all tags
2. Pasted them into an text editor modify the list as u like and join the lines by , (search and replace '\n' with ',' or use IDE actions)
3. Copy the one long line and paste it to the add/remove tags from contextmenu -> manage tags. Make sure all the items are still selected and the [ ] remove button is checked. I dont know how many letters are allowed in this field but for me it worked multiple times for bulks of around 30 tags.
