The XLS file suffix is xlsxenx. There is also a docenx suffix on Word files. How can I read them on another computer? My Acer Aspire has expired. If I buy a new one, surely I should be able to read these files on my wife's laptop which is another make. I was running Windows Vista.
Use the other laptop to remove the encryption because the files will be recognized as being encrypted. Also, in these cases the password is stored right into the files which makes it easier to decrypt them if you have the software.
