Morning All

I'm not trying to gain access to files here, what I need to do is simply check files that people are uploading to make sure that they don't have a password. File types are the common ones, i.e. Word, Excel, PDF etc.

Currently I use Neevia, but this requires reading the entire file into memory and I'm dealing with files that can easily be 200MB plus, so it takes a damn long time.


Thanks for any help...

Hi,
I am not aware what Neevia is.
But as java gives canRead() method in File class
there might be some provision to check if the file is readable or not
if it is passing this test, you can continue with the uploading.

File.canRead checks whether the current process is allowed to access a file - it is not about file content at all.
