When using a windows saved path on a linux system BAT was not able to
find all files. This was due to mixed paths (posix_path/windows_path)
the whole of the windows path was threaded as a single path by pathlib.
As in blender it is not allowed to use \ and / in filenames we can
assume that we can convert them to a single pathlib and continue.
as BAT leans a lot to posix path this path will replace all '\' to '/'
in order for pathlib to interp the file correctly.
