What are APW files and how to open them

Are you having problems opening an APW file or are you simply curious about its contents? We're here to explain the properties of these files and provide you with software that can open or handle your APW files.

What is an APW file?

An .APW file is an Any Password Data file.

Any Password Data files are used by the Windows program Any Password, made by RomanLab Co. Ltd., to store collections of passwords, user IDs, notes, URLs or program references, and related metadata in an encrypted format. They serve as a secure repository for password-type data so that only the correct master password unlocks their contents.

The program writes these files when a user saves or updates password information in Any Password or Any Password Pro. The encrypted file may include multiple entries grouped in folders, each entry typically having fields like the account or record name, associated program or URL, password, optional comments, and possibly attachments or links. To read, edit, or search these entries, the Any Password software opens the file after validating the master password.

Files begin with a two-byte signature: ASCII characters "AP" (hex 41 50) at the start of the file (offset zero), identifying them as this format.
