I'm trying to find a document manager/repository (WinXP) that can be used from a USB disk. I would like a tool that will allow you to add all documents into a single repository (or a secure file system). Ideally you would login to this portable application to add or retrieve a document and document shouldn't be accessible outside of the application.

I have found an application called Benubird Pro (app is portable) that allows you to add files to a single repository, but downsides are that it is not secure and the repository is always stored on the PC and not on the USB disk.

Are you able to recommend any other applications?

Have a look at TrueCrypt, seems like it would do most of what you're after. You can store the encrypted file system on a USB drive easily enough and then mount it as a drive (after supplying the key, of course).

Main Features:

  • Creates a virtual encrypted disk within a file and mounts it as a real disk.

  • Encrypts an entire partition or storage device such as USB flash
    drive or hard drive.

  • Encrypts a partition or drive where Windows is installed (pre-boot

  • Encryption is automatic, real-time (on-the-fly) and transparent.

  • Parallelization and pipelining allow data to be read and written as fast as if the drive was not encrypted.

  • Provides plausible deniability, in case an adversary forces you to
    reveal the password:

  • Hidden volume (steganography) and hidden operating system.

  • Encryption algorithms: AES-256, Serpent, and Twofish. Mode of
    operation: XTS.
