Re: [fpc-pascal] mciSendString with long file names
A solution I started using, because the mci commands (for some reason) don't handle all mp3 files I have, was to use a dll called fmod.dll. It handles several formats, not just mp3, and it can be started on another thread, then ignored. I've used it to build a much better mp3 player than I was able to make using the mci commands, since now I can handle other formats as well, which helps since interestingly enough, I'm still finding files in other formats burried in my collections, and so far, the fmod program handles them all nicely It can't be used in a commercial application, but it doesn't sound like yours is, so you should be ok.

Sorry for the confusion. Let me clarify: The freepasal program is always run on a Windows system, mciSendString is a Windows function.

Re: [fpc-pascal] mciSendString with long file names
That's on windows, you said the program was running on linux. In that case, backslashes will escape the spaces, allowing the path to be found properly. Windows paths are different, as mentioned before, they can be escaped too, but the character is different.

Re: [fpc-pascal] mciSendString with long file names
Won’t backslashes before each space be defining a subdirectory? If my path looks like: C:\Program Files\My Program\Some File.MP3 I don't see how changing it to: C:\Program\ Files\My\ Progam\Some\ File.MP3 can possibly work.. it's just butchering the path.
