ignore all steps below til IE, Download and FTP section. Extract it somewhere for safe keeping.
Now open up Control Panel\Add/Remove Hardware\
Other Device\Have Disk,point it to the .inf file you extracted earlier.After Ramdrive is
installed,change the size to something bigger (default is only 1MB). Open up "Registry" to :
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Ramdisk\Parameters
Only keys to change are DiskSize and DriveLetter
Windows will assign the "DriveLetter" as Z: you can change it to any letters you like by right clicking it and modify. Use a letter you've not got used.Go over "DiskSize" key,modify its value to "1f00000" without quotes. This is maximum size Ramdrive is designed. Close "Registry",
Reboot.After Reboot, redirect IExplorer Caches to New Ramdrive. Open IExplorer
Properties\General\ Settings (Temporary Internet Files)\Move Folder. Direct it new Ramdrive. At same time, slide down the "Amount of disk space to use" to 5MB, you'll free 25MB for Downloads Cache.Redirect your download manager default download location to your new "Ramdrive". Download Accelerator users can do so by going to Download Accelerator\ Downloads\Options change "Default Download Directory" path to Ramdrive. Close,save settings.
If using any FTP Manager or Client, redirecting Local Initial Folder to Ramdrive would boost performance too. You will really notice that your uploads fly.
