The recycle bin in Windows 7 is the same as the recycle bin in Windows Vista. Its the system trash can where you can delete your files and manage deleted files. The only thing that is different from its predecessor operating systems is that you can customize space allocation of recycle bin in windows 7.
The default settings for allocating space for deleted files that go to the Recycle Bin may be set to high (especially if you use large capacity drives). You can customize the space set aside on each drive or turn the feature off for any or all drives. To change the amount of space allocated, follow these steps.
1. Right-click the Recycle Bin and select Properties.
2. Select each drive and use Custom size to input the desired space to be allocated or select Do not move files to the Recycle Bin to turn the feature off for the selected drive.
3. Click OK.
