Look at the autorun file.

For 64bit you will see the lines:

[AutoRun.Amd64]

open=sources\sperr32.exe x64

Also, on 64bit installs, on the root of the drive you will see this file:

Bootmgr.efi

    I have couple of Windows 7 installation folder in my machine.

    How can I identify which one is 32 bit and 64 bit ?

    I tried checking few .ini and .inf files but none of it could give me a hint.

    Is there a way to check a file from installation folder which would tell me its 32 bit or 64 bit or both ?

      System32 for 32 bit, and SysWOW64 for 64bit? Is this what are you looking for?

      No, This is after the installation. I am talking about the installation cd itself, contents of ISO.
