删了也没事 删完后 你在ECLIPSE里看不到你的项目了 不过没关系 重新导入就行
另外你对ECLIPSE的一些设置也恢复默认了 没关系 重新设就好了

另外里面还记录有本地源代码修改历史（你源代码不同版本的备份）。

比如说 你当前workspace 中存在4个工程， 当前有几个Java文件的Editor 打开。 在eclipse关闭再打开他还会保存这些信息
在“.metadata”的文件夹 中存储了记录当前的这些信息，当然不只上面的信息还有很多其他的 东西

我在外网上找到的，不是太好。
Metadata is structured data which describes the characteristics of a resource. It shares many similar characteristics to the cataloguing that takes place in libraries, museums and archives. The term "meta" derives from the Greek word denoting a nature of a higher order or more fundamental kind. A metadata record consists of a number of pre-defined elements representing specific attributes of a resource, and each element can have one or more values. Below is an example of a simple metadata record:
Element name
Value
Title
Web catalogue
Creator
Dagnija McAuliffe
Publisher
University of Queensland Library
Identifier
http://www.library.uq.edu.au/iad/mainmenu.html
Format
Text/html
Relation
Library Web site
Each metadata schema will usually have the following characteristics:
* a limited number of elements
* the name of each element
* the meaning of each element
Typically, the semantics is descriptive of the contents, location, physical attributes, type (e.g. text or image, map or model) and form (e.g. print copy, electronic file). Key metadata elements supporting access to published documents include the originator of a work, its title, when and where it was published and the subject areas it covers. Where the information is issued in analog form, such as print material, additional metadata is provided to assist in the location of the information, e.g. call numbers used in libraries. The resource community may also define some logical grouping of the elements or leave it to the encoding scheme. For example, Dublin Core may provide the core to which extensions may be added.
Some of the most popular metadata schemas include:
* Dublin Core
* AACR2 (Anglo-American Cataloging Rules)
* GILS (Government Information Locator Service)
* EAD (Encoded Archives Description)
* IMS (IMS Global Learning Consortium)
* AGLS (Australian Government Locator Service)
While the syntax is not strictly part of the metadata schema, the data will be unusable, unless the encoding scheme understands the semantics of the metadata schema. The encoding allows the metadata to be processed by a computer progr
am. Important schemes include:
* HTML (Hyper-Text Markup Language)
* SGML (Standard Generalised Markup Language)
* XML (eXtensible Markup Language)
* RDF (Resource Description Framework)
* MARC (MAchine Readable Cataloging)
* MIME (Multipurpose Internet Mail Extensions)
Metadata may be deployed in a number of ways:
* Embedding the metadata in the Web page by the creator or their agent using META tags in the HTML coding of the page
* As a separate HTML document linked to the resource it describes
* In a database linked to the resource. The records may either have been directly created within the database or extracted from another source, such as Web pages.
The simplest method is for Web page creators to add the metadata as part of creating the page. Creating metadata directly in a database and linking it to the resource, is growing in popularity as an independent activity to the creation of the resources themselves. Increasingly, it is being created by an agent or third party, particularly to develop subject-based gateways.
