How to ensure the file path information in Matlab uialert windows is not abbreviated?

Below is my code:
File_W = fullfile(Path, 'Output', ['Test_.xlsx']);
message = sprintf(['An Excel file named ', File_W, ' has been generated!']);
uialert(app.mainWindow,message,'success','Icon','success');
It is very important for the file path information to be displayed in my uialert window. Unfortunately, Matlab decides to abbreviate to something like Volumes/Folder/../Output/Test.xlsx.
Is there a way I can force Matlab to do the right thing?

Path=strrep(Path,'..',''); % remove ellipses from Path (irrespective of position)
However, they may be significant -- the result of
Volumes/Folder/../Output/Test.xlsx
and
Volumes/Folder/Output/Test.xlsx
aren't the same.
You need to go back to where Path was set to see where/why the ellipses are there to be able to get to the particular subdirectory/folder without the reference.

Which OS? It might be an OS charateristic given the particular abbreviation.
Locally on Windows, the sprintf fails with an attempt to interpret the backslash in the file name as special characer,
>> message = sprintf(['An Excel file named ', File_W, ' has been generated!']);
Warning: Escaped character '\U' is not valid. See 'doc sprintf' for supported special characters.

but
>> Path=cd
Path =
'C:\Users\Dxxxx\Documents\MATLAB\Work'
>> message = ['An Excel file named ', File_W, ' has been generated!']
message =
'An Excel file named C:\Users\Duane\Documents\MATLAB\Work\Output\Test_.xlsx has been generated!'
>> uialert(hUIF,message,'success','Icon','success');
>>
displayed the whole string wrapped...(Win 10, R2022b)
