System Information
Operating system: win10
Graphics card: rtx4090

Blender Version
Broken: 3.3, 3.6. 4.0
Worked: Presumably never

When importing an FBK from a system location that passes through a symlink or junction the importer will process for a while, then fail and report that the file was not found.

FileNotFoundError: [WinError 3] The system cannot find the path specified:

Exact steps for others to reproduce the error

System must have a junction or symlink folder bridging between two drives.
Import an FBX from the junction location to a blank scene. In the case of a bridge between C:\ and D:\ where the FBX exists on D:\ the import path should be through C:\symlink_folder\file.fbx
The process will churn for a while and eventually fail.

No sample file because this is system configuration dependent.

Importing through a symlink or junction works fine here, please post the full error.

Please excuse the gibberish folder names, but out of concern for adhering NDA I've scrambled the names while keeping the same character count in the very off chance there were a character limit issue.

Windows itself has a 260 character limit on paths which might be part of the problem here: https://learn.microsoft.com/en-us/windows/win32/fileio/maximum-file-path-limitation

The path from the original error message is cut off very close to that limit. You can see it's not actually the entire path and is missing the remaining \text\'A136371TLirLirp_TouringP000A1CutsPart1.fbm\A136371TLirLirp_TouringP000A1CutsPart1_50M16K_u1_v1.png portion of the filepath.

The error has occurred in the bpy.path module called from the bpy_extras.image_utils module, both of which are part of Blender's Python API and not the FBX importer, so I think it's likely that if there is a code issue here, the issue should be re-created over at https://projects.blender.org/blender/blender/issues.

Going to line 1760 of C:\Program Files\Blender Foundation\Blender 3.6\3.6\scripts\addons\io_scene_fbx\import_fbx.py and adding the verbose=True argument to the function call will print the imagepath(filepath) and dirname arguments, that were passed to the bpy_extras.image_utils.load_image function, to the System Console. Printing something like load_image('<imagepath>', '<dirname>', ...).
If what's printed is not the unscrambled equivalents of
C:\files\new\junct_folderd\xyx\sources5\sources5_cur\cal_to_hela_larger\textures\vip_xyx_map_to_hela_larger_bungo1\Assets\Models\..\..\..\..\..\..\..\..\..\..\..\Users\steveinaba\Downloads\A136371TLirLirp_TouringP000A1\A136371TLirLirp_TouringP000A1CutsPart1.fbm\A136371TLirLirp_TouringP000A1CutsPart1_50M16K_u1_v1.png
and
C:\files\new\junct_folderd\xyx\sources5\sources5_cur\cal_to_hela_larger\textures\vip_xyx_map_to_hela_larger_bungo1\Assets\Models\, then I would mention what they actually were.

    image = image_utils.load_image(
        filepath,
        dirname=basedir,
        place_holder=True,
        recursive=settings.use_image_search,
        verbose=True,  # New line
        )

I did notice that the path from the original error message is cut off before the . in the directory containing a . character, but I can't think of any reasons why the path might accidentally be cut off at a . specifically.

A little odd is that looking at the line of code that raised the error, in order to call _os.listdir(dirpath), it must have first passed the _os.path.isdir(dirpath) check that checks whether the path is a directory that exists (_os is just an alias of the os module in the file in question).

The error has occurred in the `bpy.path` module called from the `bpy_extras.image_utils` module, both of which are part of Blender's Python API and not the FBX importer, so I think it's likely that if there is a code issue here, the issue should be re-created over at https://projects.blender.org/blender/blender/issues.

Going through the discussion, the issue here seems to be related to reading filepath or path limit, and not related to FBX i/o
Closing in that case. Please report bug at https://projects.blender.org/blender/blender/issues with possible way of redoing it locally.
