Hi Davendra,
The files that you have are encrypted with SEE Removable Media/ Storage, and hence have the .xml extension.
To access this files you will either need to have SEE install on the other machine, else you can copy the Removable Media Access Utility from the orignal machine on the external drive and then access the files using it on any other non SEE machine, the only requirement will be the password/certificate used to encrypt the file.
