I have a task where I have around 300 files and for those files, I need to assign a certain level of permission based on the person. For example, I have files A, B, C, and D, and only person X can view those files. How can I do this in bulk and not one by one? sharepoint files SP lets you change access by clicking on the file and then by clicking on "i" on the right side of the SharePoint where you will find "manage access", however this only works for one file and you cannot do this with many files.
