I have message saying disk space is low. In Computer Management screen ACER (C:) is showing capacity 16.45GB free space 439MB and ACERDATA (D:) is showing capacity 17.66GB and free space is 17.38GB. How do I activate (D:) so that disk bets some use? Thanks Graham

try using disk cleanup. Start>programs> accessories>system tools>disk cleanup choose c: drive and tick all boxes and delete.

Yes take a look at your drive manager in windows.
(Right click) Computer - Manage - Disk Management.
This will show you how your drives are setup.

The simplest solution is to run Disk Cleanup as follows....
1. click start then hi-light All Programs > Accessories > System Tools and click on Disk Cleanup
2. wait while Disk Cleanup calculates how much space you will be able to free on ACER (C:)
3. in the Disk Cleanup for ACER (C:) under Files to delete:
4. click to set the check-boxes of the groups of files you wish to delete
5. at bottom of the list is the Total amount of disk space you gain
6. click OK button and on Disk Cleanup for ACER (C:) pop-up, click the Yes button
7. redo the preceding, clicking on the More Options tab to free more disk space from other areas.

Install a partition manager program like
http://www.partition-tool.com/personal.htm
open it and you will see the entire hard disk. In there either create another partition in the unallocated space or add it to the D partition.

To increase the capacity of formatted disk space on your computer, you will need to go to Disk Management. This can be found under the Control Panel, Administrative Tools, and Computer Management. Under the Control Panel's category view, Administrative Tools can be found under Performance and Maintenance.

On the left pane, you will see several options. Disk Management is available under Storage. You will definitely be able to format your unpartitioned space here. However, you may or may not be able to expand your C Drive space with this option, it may end up becoming a D Drive, or another letter of your choosing.

If this does not work to extend your C Drive space and adding a second drive letter is not an option for you, you can either reformat to receive the entire available disk space, or, if you prefer, there is commercial (such as Partition Magic), and potentially free, software available to perform this.

Please let me know if I can be of any additional help. Thanks!

try removing some unwanted programs. run disk cleanup, then defrag

pls try to go in safe mode and disable this warning system of low disk space from control panel and then free up some disk space for ur system to boot properly

1. just go to my computer right click on it go to ' manage' > disk management > right click > on your pen drive allocation > partion then you can format it and you can get your memry back thanks

Try this first:
Right click my computer, then go to manage, then go to disk management and look for the removable disk (your flash disk) then right click it and try to delete and create partition. then format.
