上传文件时提示 “磁盘空间不够”的问题

一个测试站点，在前几个月当中，发布产品时有一个上传产品图片功能，前几个月上传都没有问题
现在碰到一个问题，只要是上传一个很小的文件就提示 空间不够，而实际上空间还有300M没有用到，

在网上我也找了些资料，具体网址：http://www.goldot.com/Forum/printpage.asp?BoardID=19&ID=36



我现在上传时提示的错误代码如下，附件中也有图示。

------解决方案--------------------
是不时上传目录灭有权限?
------解决方案--------------------
我遇到过这个问题，哈，打包后重新上传后解压缩就可以了。

具体原因不知道。

------解决方案--------------------
用优化大师等软件做下系统清理，有可能是IE的缓存文件达到上限了，试试看。
------解决方案--------------------
可能是真的没有空间了，
系统不会说慌。
