Hello.

As I mentioned, I’m developing a file manager and I’m having trouble handling files whose path or filename is longer than 63 characters.

Is there any way I can copy them?

When I try to do so, I get that error for files whose path and filename together exceed 63 characters, and I’m not sure what to do.

Thank you.

An experiment to try, don't know if it will work.

Before copying change the working directory to the one containing the file (maybe CHDIR twice if its a very long path) and copy from there.

If the destination path is also very long you may need to copy to a short directory path first then CHDIR to the long destination path and copy again.

Thank you very much for the suggestion. It’s certainly tempting.

For now, I’ve switched to RP2350, which, with its 127 characters, should be enough.

Best regards.
