That is not always possible, since application directories tend to be protected.

The inquires asks not about application directory, but about working directory. They are, generally, different directories.

Read the last sentence again; it is quite ambiguous.

Sergey Alexandrovich Kryukov 14-May-15 12:12pm

Yes, of course, but this is because the inquirer is quite confused. But thank you for the note, it makes your warning perfectly valid and important. I added a new paragraph to my answer, to try to un-confuse him.

So where should it save the file?

You should use Reply button, that way people get notified when you reply to them. To your question: is the file specific to the user who uploaded/saved it?

If this is an application with UI, the best option for most cases would be using "Save As" dialog, so the user would be able to choose the directory.

However, using a working directory is quite typical, especially for console-only applications. Apparently, this directory could still be considered as a part of the user input: this is the directory where the user started the application. If you do it this way, you can use the file name without path, because the working directory will have precedence. Note that the application directory and working directory are different directories: a user can start the application in any directory.

[EDIT]

Also pay attention for our discussion with Richard MacCutchan, who gave you important warning about application directory. This is the directory where you executable module is placed (which is, in turn, has nothing to do with the installation; the application can work without any installations). Generally, this directory is intended to provide only read-only access to files.

Working directory is something different: this is where the user chooses to start the application (and the application can later change it), the default directory for relative path names. If the user choose the directory with write access (which is can be well expected), writing will be possible. :-)

[END EDIT]

For finding the directories associated with some application explicitly, please see my past answers:
How to find my programs directory (executable directory),
How to find my programs directory (current directory, "special folders").

Never use string concatenation and other string operation for finding file names and path names. Note some useful methods of the class System.IO.Path, in particular:
https://msdn.microsoft.com/en-us/library/system.io.path.combine%28v=vs.110%29.aspx[^] (do not concatenate, use these methods!),
https://msdn.microsoft.com/en-us/library/system.io.path.getfilename(v=vs.110).aspx[^],
https://msdn.microsoft.com/en-us/library/system.io.path.getfilenamewithoutextension(v=vs.110).aspx[^],
https://msdn.microsoft.com/en-us/library/system.io.path.getfullpath(v=vs.110).aspx[^], and so on.

Ok, for doing this job you need to figure out about current execution file path, in .Net for this purpose we have several ways some of the most useful ways are:
First part:

C#

string exePath = Application.ExecutablePath;
string startupPath = Application.StartupPath;

Or

C#

System.Reflection.Assembly.GetEntryAssembly().Location;

Or

C#

string path = System.IO.Path.GetDirectoryName( 
      System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase );

But I prefer first one. ;-)
Then you need to make sure you have a read and write permission at this directory, basically when you are installing application under one of the system users you will receive demanded privilege from user account service so you don`t need to care about it, however you can also set other user and permissions at the second part of this job.

Second Part:
This part is really depend on your PDF creation module, but by assuming the most poplar way to doing this business you will need to use System.IO library. But for setting permissions try to look at the below links:
FileStream Class:
https://msdn.microsoft.com/en-us/library/system.io.filestream(v=vs.110).aspx[^]
Directory.SetAccessControl Method:
https://msdn.microsoft.com/en-us/library/system.io.directory.setaccesscontrol(v=vs.110).aspx[^]
FileInfo.SetAccessControl Method:
https://msdn.microsoft.com/en-us/library/system.io.fileinfo.setaccesscontrol(v=vs.110).aspx[^]
