SanDisk SecureAccess V1/V2 Vault Structure (2010–2011) – Cruzer Blade & Extreme USB 3.0

Hello,

I am trying to reconstruct and open some old SanDisk SecureAccess vaults created between 2010 and 2011 on SanDisk Cruzer Blade and SanDisk Extreme USB 3.0 drives.

I am looking for technical information regarding the vault structure used by:

• SanDisk SecureAccess

• SanDisk SecureAccess

• Club SanDisk / early SecureAccess releases around 2010–2011

Questions:

1. What was the exact folder structure of a V1 vault?

2. Did V1 use 8-character hexadecimal .dat filenames as encrypted containers?

3. What files were mandatory for a V1 vault to open correctly (encrypted_list.txt, seed files, profile.dat, etc.)?

4. How did the structure change in V2?

5. Did V2 use 16-character hexadecimal .dat filenames?

6. Were files such as:

   • index.idx

   • vault.db

   • filexxxx.db3

   • compressed_seed.txt

   • encrypted_list.txt

   part of SecureAccess, Dmailer, or both?

7. If an entire V1 vault was copied into a new V1 or V2 vault, would the original encrypted .dat files retain their filenames, effectively creating a “vault within a vault”?

8. Does anyone have screenshots or directory listings from original 2010–2011 installations on:

   • SanDisk Cruzer Blade

   • SanDisk Extreme USB 3.0

My goal is not password recovery. I have the password. I am trying to recreate the correct file structure from recovered files obtained from a USB image.

Any technical documentation, screenshots, old backups, or directory examples would be greatly appreciated. And rewarded.

Thank you.
