ERROR: Primitive '_FilePos' failed when using SimpleMIDIFile.read(pathName)

[BroCorra]

Hi everyone, I'm using Supercollider 11.2 in Windows 10.
I have the right extensions required form the official documentation, in the following folder:
...\AppData\Local\SuperCollider\Extensions\SC3plugins

Every time I call the SimpleMIDIFile class I get the following error:

`ERROR: Primitive '_FilePos' failed.
Failed.
RECEIVER:
Instance of File {    (000001FCE7C4EB08, gc=A8, fmt=00, flg=00, set=02)

}

^^ The preceding error dump is for ERROR: Primitive '_FilePos' failed.
Failed.

What could be the problem?

can you check if your file exists?

File.exists("your\path\to\the\file")

Thanks for this, actually the probem was related by the fact that the file was somehow unaccessible. I suggest the ones who have this issue to check the file permissions.

thanks @telephon
