Where does the "Permanently accepted certificates" get saved in the RTC eclipse clients

The older certificate is stored in the same location as the root directory of the RTC Eclipse client workspace, in the folder .jazzhostnamecerts

This file can be manually updated with the newer certificate using the following instructions:
1) Get the newer certificate deployed by the admins using the following steps:
    a) Open Firefox options (Tools-> Options).
    b) Click  Advanced -> Encryption -> View Certificates.
    c) Search for the accepted certificate and then export as a "crt" file.
 ** If you are using Internet Explorer Goto Tools -> Internet options -> Content tab -> Certificates and Export the new certificate as .cer file.

2) Import this newly extracted certificate into RTC Eclipse environment using the following instructions:
    a) cd to  <RTC-Client-Install>\jdk\jre\bin drectory
    b) Run the command:
keytool.exe -import -trustcacerts -alias rtc -file "<Location_of_Exported-Certificate>.crt" -keystore "<RTC-Client>\jdk\jre\lib\security\cacerts"
    c) Now try starting the Eclipse client, the screen to accept certificate would not popup any more.

There was a doubt on what is the root location (of the workspace), so I would like to put in a screenshot, for easier identification:
