Description

I use Guacamole for users to connect in RDP on a Windows Server 2019 on restricted accounts. Users don’t have access to File Explorer. They use a software that can export files (word, excel, pdf) to then read them via suitable software.

In order to be able to retrieve these files, users attempted to export (save) their file directly to the Guacamole \\tsclientshare-folder\Download folder. At this moment, the file is well downloaded, but this one is almost empty and unreadable, and the software also display an error. I have these logs on my server:

My theory is that the program first saves a temporary file which it bases on to create the real file. Maybe there is a way to add a delay to the transfer to give it time to save? But maybe the problem is somewhere else...

I have the same problem when I save a document with word processing software (LibreOffice) and with a PDF reader (FoxitReader).

Thanks for your help
