But i read articles saying if set as boot drive all your documents eg: pictures musics downloads will go in there i do alot of download so my ssd will run out very fast can i change the directory of those documents or there is some settings to make the ssd a boot drive only?
Your Internet Explorer temporary files, Google Chrome cache, Firefox cache, programs' settings, etc. will also ate up those space, you can however change the My Document's directory to another drive (partition/volume) by follow steps below: (Note: Windows 7/8 only)
1. Library > Documents, right-click > Properties.
2. Left-click "Include a folder", choose the folder you want, click "Include folder".
3. Click on the included folder to highlight (select), click "Set save location".
4. Click on other folders, click "Remove" to remove them all.
Use above steps for your Picture and Video as well so the default folder will be on other drive than your C drive.
For Internet Explorer (7 and above)
1. Tools > Internet option.
2. At Browsing History (I.E. 7 might be slightly different), click "Settings".
3. Click "Move Folder", select the folder that you want to reside, click "OK".
4. Re-login (log off and login again) to activate this setting. (System will copy all the temporary files over to the new location)
For other browser, I'm can't find such options to move the cache, unless you use the Portable version of the browser.
Hope these help you reduce the usage of the C drive.
