Adobe目前正在对PDF格式进行标准化，使得不符合标准或低于标准的PDF文件将无法打开。这可能使文件不可访问，导致数据丢失。让我们看看如何消除这些问题。
便携式文档文件(PDF)格式是继微软Word之后世界上使用最广泛的文件格式之一。该格式非常适合在组织中存储和传输信息，因为该文件几乎与所有阅读器和编辑器软件兼容。查看PDF文件也很容易，无论是在线还是在物理系统上。例如，没有在系统上安装任何阅读器文档的用户可以使用谷歌Docs在线查看文档，这是搜索引擎谷歌提供的基于云的文档创建、编辑和查看服务。该软件套装还允许用户恢复无法在电脑软件上打开的PDF文件。此外，该文件格式是存储信息的最安全的文件格式之一。使用PDF文件存储有价值和敏感信息的人可以通过在文档中添加密码保护来防止文档被未经授权的人打开。PDF文件格式是Adobe在1993年首次推出的，旨在允许用户存储极其大量的数据，这些数据可以通过电子邮件或可移动存储设备轻松传输，允许大量的人同时处理相同或不同的PDF文件。这种易用性导致几乎所有人都以这种格式创建和共享文件。但是，当用户使用adobeacrobatreader以外的软件创建PDF文件时，会出现错误。 This is because with every new version of Adobe Reader, the company is trying to set standards for creating PDF files. Earlier, these errors did not occur as there was less standardising of the file format. These errors can be very frustrating as they make the file inaccessible. Then the need to recover PDF files arises. Errors also occur when the PDF file is not created properly. If the file is created using Adobe software, then it would up to the standards prescribed by Adobe, however, if created using duplicate software, then the files might pose some problems. Most of the time, when such errors occur, software either fails to open the file or opens a blank document. Some of the most common errors that users have to deal with are “Too few operands” or “’An unrecognized token was found”. They occur when the file is not upto the standards. If the PDF file shows errors while opening, it means that the file has got corrupted. If users are using the latest version of the Adobe Reader software, then they can try to open the file using a different software. They can also try to open the file using older versions of the Adobe Reader software. PDF files also tend to not open when they are sent via email as an attachment. In order to prevent this, try sending the PDF file in a zip file, it eliminates the risk of the PDF file getting corrupted. Meanwhile, in order to recover PDF files, users can also use the DataNumen PDF Repair software from DataNumen.
