plzz reply with full details.

 

1.) Not possible.

2.) Nope! If u do it from command prompt, it'll just change the extension of the file but the format will be same. So use the available converters for it

3.) Don't delete those files/folders, coz they r used by avast! anti-virus. If u really want to delete them then u can use Unlocker to delete them. But it'll be of no use, coz after a reboot u'll get them back

4.) Type sysdm.cpl in RUN dialog box and goto Advanced tab. Click on Settings in Performance section. Goto Advanced tab and click on Change button. Now select System Managed Size and click on Set button.
