Hello! I bought a new computer and would like to use zotero there as I have been using on my old computer. I have the desktop version of zotero with no web storage. I noticed that on the c-drive, there is a zotero folder with a subfolder called "storage" where all the pdf files are stored. Could I potentially just copy the files there to the corresponding storage folder on the new computer and I would be able to see the pdf just fine? Or it does not work like that? Would I need to upgrade to the paid version to move my files to the new computer, since I will reformat the old one and recycle it? Thank you!
