missing files

According to ativity record, 3 files were deleted permanetly.
Could you help me to restore?

Hey ​@Lucasssso, if the file were permanently deleted I'm afraid it cannot be restored. Permanently deleting a file will get rid of the file forever for everyone who has access to it. This action cannot be reversed.

Someone with an “can edit” permission or “can view” access on the file can initially delete the file and leave it in a restorable state. They then have the option to delete it forever.
 
You can always double check your deleted tab for these. The steps for this can be found here: Delete and restore files
