Empty basket is the fastest way as in Windows release some disk space. At least when the files you first moved to the basket and then removed completely.

The amount of trash

Capacity basket preset. After installing the operating system, its volume is 10% of the disc. A 320GB disc is decent at 32 GB. That is correct. Right mouse button click on the Recycle Bin icon and choose Properties. The display, where you can set the amount of trash for each disc. At the same time, there can prohibit the use of the basket - in this case, the files will be deleted permanently.

Decrease the amount of trash dobetes that you will not fester hundreds of files that you sterli a few months ago.

Disk Cleanup

Another way how to get more space on the disk is to use the Disk Cleanup. The tool will analyze your computer and identify files that can be removed. Typically these are dozens - hundreds of megabytes. Attention! Standard marked only the files, delete where you can not cause any harm. The list of files to be removed, so it's best to explore and possibly select some of the proposed additional capacity.

After several months of Windows Vista to me this tool is proposed to erase 38,7 MB of data, but if you would have been erased all the proposed items would be 6,31 GB of additional seats.

Another opportunity to obtain additional disk space is to reduce the size of the paging file (Control Panel - System - System Properties - Advanced tab - Performance - Advanced tab - to change the virtual memory), odinstallirovanie unused programs, or, if the version Ultimate, delete shadow copies of files.
