The tracker has restrictions on the length of project file names. However, this restriction doesn’t apply when the file is renamed on a computer. If a project file is renamed on a computer and exceeds the allowed character limit, the project will not open on the hardware.
Steps to Reproduce
Create a project and save it with a compliant file name on the hardware.
Rename the project file on a computer with a name exceeding the character limit.
Attempt to open the renamed project file on the hardware.
Careful! This is a FAT32 filesystem limitation and not a bug.
There are a couple things to be aware of here:
The FAT32 filesystem has a character limit how long filepaths can be.
Certain characters are not allowed like \ / : * ? " < > |
The maximum filepath can be 255 characters - this is the entire path, not a single file.
The filesystems on computers do not keep this in mind (Windows does, but not correctly either).
Due to this, there are some limitations how long a filepath can be on the device, before it becomes a problem to be read… and there is nothing that can be done on the device once this happens, because the software simply won’t see those paths/folders. Which also means there is no way to alert the user about this.
Sidenote:
Project names are not based on the filename on disk (they are two separate values)
