Delete files from upload folder

[therapist]

I tried to install facebook plugin to the upload file and it didnt work (after the ipmort of plugin (xml file) the file was competely blank. So I decided to delete all the files coming from this plugin I copied to FTP before. Unfortunately I didnt want to but I made mistake and deleted all the files which were in this Upload folder. If I copy them back to upload folder, should it work again?
I dont have my 4.0.2 version in this computer so that´s why I am asking before trying that.

If you download the version from vb.com that you had installed and upload them to your site, it should work.... unless you had modified the files, in which case you will need to modify them again. Also, if you had attachments and avatars, etc, in the filesystem and you deleted those directories, then you will need to restore them from a backup.
