PAR file issue

Hi everyone,

I was looking for changing an existing deployed PAR file .

I have downloaded a PAR file from portal

["System Administration"==>"Support"==>"Support Desk"==>"Portal Runtime"==>"Browse deployment"==>"ROOT"==>"WEB-INF"==>"deployment"==>"pcd " ]

But when I look at the downloed file its .default file type.

[com.sap.portal.support.browse.default]

Now I tried renaming this file to PAR file through CMD and after renaming it converts to par file but I cannot see the contents when opened as a zip file.

Please let me know How excatly I can conert this file to a par file and load into NWDS and deploy it again and load into portal.

Regards,

Raj
