# [Open][Document] menu

Open the Viewer window and display the contents of documents, binders or containers.
If the file is a protected document with the use of a password, the [Password] dialog box appears. Enter an open password. If the password is stored temporarily, the document opens without asking for the password.
If the document is protected by an Electronic Signature, it opens when the Electronic Signature which permits the document to be opened is in [My Signature] of the Electronic Signature Case Tool and also the Electronic Signature Case opens.
If the document is protected by a Digital Certificate, it opens when the certificate that was used to configure the security is registered with [Personal] in the Windows Certificate Manager.
If the document is a file other than an Electronic Signature, the associated application starts and the file opens.
