Windows Recycle Bin Doubt

[Vivek788]

Recently I saw tat 10% of each drive is reserved as maximum for recycle bin.I have a 160 gb hard disk with quite big partitions...so I am worried if all those gbs of space are just 'reserved'.
Is the space allocated permanently or just used when needed?

You can change this setting. If you want to reduce(or make zero) the amount of disk space for a particular drive or all of drive you can do that by right clicking recycle bin and clicking properties.
