Well done, it can't be easy following instructions in another language
If you haven't yet permanently trashed the file you moved, don't.
it sounds from your comment "how to make Safari open with all the tabs from my Favorites" as if you previously had a folder of tabs opening when Safari starts ( en el menú emergente "Abrir nuevas ventanas con:...), and that a link or bookmark to the problem file is possibly in that folder...
In Safari, check the 'favorites' or 'bookmarks' list for that folder, & delete the link to the file - if you do find it, that was the problem & if you now quit Safari, then replace or 'put back' the com.apple.safari.plist file that you removed, things may be back to normal, along with your original configurations.
