Restrict file types

[muralidharand]

Hi experts,
How I want to restrict the users for uploading certain file types in document library?

When you say "file types" you refer to mimetypes or content types ? Probably mimetypes.

In any case I think your best option might be creating a behaviour attached to the creation of a content and throwing an error if it is not of a suitable type.

Can you please give me some samples to understand this ?

Hello,

You can find a tutorial on behaviors (with corresponding sample code) on Jeff Pott's blog:

However if you just need to prevent the access to a one single folder, a folder rule might be cleaner than a behavior.
