推荐答案

问题在于判断文件是否已损坏。



如果您没有每个文件的SHA哈希值，或类似的东西，那么唯一可以判断文件是否已损坏的方法是尝试将其作为PDF文件读取 - 如果不能，则表明它已损坏，或者使用读者软件的PDF规范的更高版本。



如果你能阅读它们，那么它们可能并没有腐败 - 你需要一个人来阅读它们并确保它们看起来像我应该怀疑的那样 - 所以你可以忽略它们。



我会通过阅读器处理它们，然后为它们设置一个SHA哈希值，以便下次可以立即检测到任何更改。

The problem is in deciding if the file is "corrupted".

If you don't have a SHA hash value for each file, or something similar, then the only way you can tell if the file is corrupted is to try to read it as a PDF file - if you can't then it is either corrupt, or uses a later version of the PDF specification that your reader software.

If you can read them, then they probably aren't corrupt - you would need a human to reader them and ensure they look as they should I suspect - so you could ignore them.

I would process them through a reader and then set up an SHA hash for them, so that any changes can be detected immediately next time.

对于仍在寻求解决arindamrudra问题的人来说，应该看一下这个免费的，开源的小程序，叫做'递归查找损坏的PDF文件'（下载链接： http://sourceforge.net/projects/corruptedpdfinder/ [ ^ ]）这样做：在一个内容中找到递归损坏或受密码保护的PDF文件用户选择的文件夹。



祝你好运。

Hi,
For anyone still seeking a solution to arindamrudra problem should take a look at this free, open source and small program called 'Recursive finder of corrupted PDF files' (download link: http://sourceforge.net/projects/corruptedpdfinder/[^]) which will do just that: find recursively corrupted or password protected PDF files within a folder of a user's selection.

Good luck.
CSilva.
