Hi Martin, Thanks for the reply, your time is much appreciated. I understand (and agree with) the reasoning behind the decisions made (and also that I fall into a very small use-case scenario). I remember when everything was marked as executable which did not make much sense but I must admit that I got used to it ;-) I had hoped that there was a policy setting somewhere that could be set to revert to the old behaviour (pre 1.0.2) but could not find any reference to it, though I must admit that I struggled to find much explanatory documentation on the web regarding the types of things that could be set, so I wondered if I was just missing something (I am glad to hear that was not the case ;-) ). To answer your question, I am developing Qt applications in C++ with various dependencies, which also often have to be rebuilt. For convenience my build directory is on an NTFS drive so that all my source is in one place, i.e. that a change in one OS is directly available in the others without having to first commit to a repo and update/etc. Normally this is okay, but I started having issues when running configure/etc. on the NTFS drive (as well as running the application itself). The first time it happened it took me a while to track down the cause. For my internal drives the fstab solution is the best, I guess, but for the removable drives it is just not practical to use any other file system than NTFS since (at this stage) it is the only one I know of that can be read/written by all the OSes we use. (Silly windows that does not support ext4 :-P ) Thanks again for the help, it is much appreciated and enjoy the weekend further.

This is overzealous, and causes quite a lot of confusion as file managers like nautilus will then ask the user whether they want to open or run that .txt or .jpg file you want to look at. Now VFAT and NTFS use the showexec mount option, which causes only .exe, .com, and .bat files to be executable (which makes them work nicely with Wine or Mono), but not all files. The case where this breaks is having Linux-ish executables on VFAT and NTFS devices, but the fraction of people who need that is so small (and also presumably knowledgeable enough to know how to work around it) to sacrifice this against more sensible behavior of data files. <div class="im"> > How do I go about allowing files to be executed on NTFS systems? </div>For a particular device/partition you can create an entry in fstab (with LABEL= or UUID=) and set the "exec" option there. <div class="im"> > Setting up all possible media in fstab is not an option as I also > work with various removable drives which need to be readable by > windows machines. </div>That's currently not possible, I'm afraid. One workaround would be to name the executables ".exe" (if you need to run them on Windows as well, they need to have this anyway), or write some small shell script wrappers with a ".bat" name perhaps. Out of interest, is that for cross-platform development with C# or similar? Mono programs are usually named .exe anyway, to be executable under Windows.
