blocked file types-SharePoint 2010

File types can be blocked on a per Web application basis or globally.

The settings are made from the operations tab of the central administration web site.

Essentially it is a list of file extensions that are not allowed. SharePoint only checks the extension and then allows/disallows it.

So if you try to upload an exe file and find that it is blocked, you can change the extension to .doc and upload the file. Antivirus checks the file content and decides whether it is a .doc or .exe file.

The default list of disallowed file extensions is as follows:

ade, adp, app, asa, ashx, asmx, asp, bas, bat, cdx, cer, chm, class, cmd, com, cpl, crt, csh, dll, exe, fxp, hlp, hta, htr, htw, ida, idc, idq, ins, isp, its, jse, ksh, lnk, mad, maf, mag, mam, maq, mar, mas, mat, mau, mav, maw, mda, mdb, mde, mdt, mdw, mdz, msc, msi, msp, mst, ops, pcd, pif, prf, prg, printer, pst, reg, rem, scf, scr, sct, shb, shs, shtm, shtml, soap, stm, url, vb, vbe, vbs, wsc, wsf, wsh

What is a Farm Passphrase ?

The farm passphrase is a new security feature in SharePoint Foundation 2010. Similar to a password, it is created as part of the initial creation of a SharePoint farm (or as a part of upgrade). The passphrase is created during PSConfig portion of SharePoint installation. It is then only required for adding additional servers to the farm.

In addition to a somewhat added layer of security, the farm passphrases main function is that it is used to encrypt the credentials for the farm administrator and other “managed accounts.” Using the new managed accounts feature is optional and the details surround its use will be covered in detail in another module. Just Keep in mind that managed accounts are similar to traditional service accounts except they are managed by SharePoint. Because the credentials for these managed accounts can be encrypted by SharePoint, SharePoint also now has the capability to access account credentials and use them. For example when creating a new Web application, an administrator can select and associate a managed account to the Web application without having to know the password for that managed account. Using the encryption key created using the farm passphrase, SharePoint will be able to decrypt the credentials for any managed account. Administrators will thus potentially not have to know the passwords for any accounts managed by SharePoint, which can be a big plus in a least privileged security environment.

is it possible to set up Quota for Subsites in SharePoint 2010 ?

Site quota management is very important to control the resources in site collections. We all know that site quota can applied at the site collection level only in SharePoint Server 2007 but now the question: is it possible to set a storage quota on individual sub-sites within a site collection in SharePoint 2010?

The answer is: the same situation persists in SharePoint 2010 also. Quota templates are applied at the site collection level in SharePoint 2010 as well.

To know the complete details then please refer this: http://technet.microsoft.com/en-us/library/cc263223.aspx

Still if you wants to know how we can calculate the subsite storage then please let me know, Thank you

Site Collection Quotas

When you set a quota limit for storage, you can set two values: a warning value and a maximum value. When a site collection passes the warning limit, an e-mail message is sent to the site administrator and owner notifying them that their site collection is near to their storage quota. E-mail messages are sent daily until the storage level drops below the warning level. When a site collection meets the maximum limit, another e-mail message is sent to the owner and administrator, and no new content can be added to the site collection.

There are 2 important questions based on site quotas, such as:
