I reinstalled PSE after my computer crashed. Installation went fine but I failed to import the keyword tags. Is there any way to import the keywords now that the photos have been imported? Is it possible to attach my keyword tags after the fact? Any help is appreciated!
Is it possible that your old catalog has been saved? If so, you only need to open it using the File>Catalog Manager. Or, if you have a backup of the catalog, you can restore it.
If you no longer have the catalog to work with, you would need to create a new catalog. If you are importing the images with keyword tags, a dialog will appear asking if you want to import the keywords. Respond yes, and they will be available in the tag hierarchy under the Imported Keyword Tags category. From there, it is fairly easy to click and drag the tags to your desired hierarchy. However, you will lose any People, Places, Events tags (unless they were first created several versions ago).
I don't want to say "I told you so" but you should always keep a backup of your catalog. Even if you don't want to do a full backup with all your media (and why wouldn't you?), you can save just the catalog folder by copying it using Windows Explorer. A catalog folder is fairly small and if it is safely backed up, it can save an enormous amount of time when restoring a computer from a crash.
Thank you for your very clear explanation. And yes, you can say "I told you so" because, as you suspected, I failed to have my catalog backed up. Today I backed them all up and I hope in the future I won't have to add any more keywords except for new photos. Thank you again, you've been very helpful and I've learned my lesson.
