Bug Description

When trying to open a .pdf file from a UNC path (such as \\%COMPUTERNAME%\C$\Temp\test.pdf) results in an error:

Error annotate PDF file "\\my-pc\c$\Temp\test.pdf"
Document not loaded! (\\my-pc\c$\Temp\test.pdf), Unknown error

When trying to set the PDF background to a UNC path (using the "Missing PDF background file" dialogue), Xournal++, too, reports an error saying:

Error reading PDF: Document not loaded! (\\my-pc\C$\Temp\test.pdf), Unknown error

Opening .xopp files from a UNC path works.

Expected Behaviour

Much like .xopp files, .pdf files (and thus PDF backgrounds) should be able to be loaded from UNC paths.

Steps to Reproduce

1. Download a PDF to the C: drive
2. Open the file location in your file explorer
3. In the address bar, replace C: with \\%COMPUTERNAME%\C$
4. Try to open the .pdf file in Xournal++
5. Take note that the described error occurs

That's a known issue. Currently, it is not supported, since we mix many different file handle drivers. Some do not support remote paths.

Thanks for the rapid answer!
I was kind of wondering bc I couldn't find a related issue.

Feel free to close it in case it's a duplicate.
