I don't think this is a Windows mistake. I can edit a "hidden" file in my text editor and save it. I cannot save a "read-only" file in my text editor. So the metadata seems to be working correctly on Windows. Therion is the only program I have which thinks it cannot write to a "hidden" file. This might be a limitation in Tcl/Tk's methods for opening a file. (MFC has a similar problem with CFile::Open in C++, for example.) Maybe it expects you to open an *existing* file using the same attributes as it already has. So if a file exists and is "hidden" and you try to open a file write stream without "hidden", it might refuse since the file exists without that attribute. The solution here would be either: if file_exists(filename) foo = open_file_with_attributes(filename,'w',get_attributes(filename)) else foo = open_file(filename,'w') or: foo = open_file(filename,'w') if !foo foo = open_file_with_attributes(filename,'w',hidden) But of course, I do not know Tcl/TK, so I cannot write this in proper code, only pseudo-code. The big issue here is when you share files between different computers, you can end up with one of them setting the "hidden" attribute for you, since the filename starts with a . character, and on Linux, that gives it "hidden" status automatically. When you copy the files from Linux to Windows, your copying tool (Gareth is using PCloud with a standard Windows mapped drive) may choose to give the file a "hidden" attribute, since that is what is automatically had on Linux. So files can easily gain a "hidden" flag because Therion creates lots of files with a "." at the start of the filenames. _______________________________________________ Therion mailing list Therion@speleo.sk https://mailman.speleo.sk/listinfo/therion
