    Windows 11 Filename truncation


    Hello,Recently, I have been developing an app and I noticed something strange. Suppose I have a file with long name e.g. WGS - Comprehensive Coverage Services of WGS MCP and Tech Refresh of MCP Equipment WGS00024ETT1832103_Project Proposal_19 WGSDGD-DGD-2003-1 - Cover Letter with Project Proposal. When I upload a file with this long name on Windows 10, the filename displayed in the console is exactly the same as the original filename. However, when I upload the exact same file on Windows 11, the filename displayed in the console is clearly a truncated version. Is this expected behaviour? I

    Filename Truncate Bug

    This has to be a bug, and I can't believe no-one else has posted about it.

    I've tried searching to see if anyone has noticed this problem, but can't find anything, seems it's quite difficult to find the right search terms.

    ---

    When resizing a column in an explorer window, if the length of the filename exceeds the width of the column, an ellipsis is displayed showing that it has been truncated. This is normal expected behaviour.

    However, if less than 4 characters are truncated, the ellipsis is missing and the filename is just clipped.

    This is highly annoying, very confusing and simply needs to be fixed.

    This is true for every column type (filename, type, size, date modified, etc); and not only just regular explorer windows, but also any application that uses the explorer shell in its dialogue boxes.

    It is everywhere, and I've also checked not only my PC at home but also four other PCs all running Windows 10. They all exhibit this bug. So it cannot be a conflict arising for certain software being installed or anything like that.

    Try opening an explorer window and see for yourself...

    (I also posted this on the windows feedback hub, but for some reason couldn't sign in, and therefore can't track the progress. And the ability to search the hub seems to have been removed.)

    Long filenames not truncating on desktop

    Hello!

    Here is the issue. When i select a file located on desktop, there isn't a grid space limit applied to the text, the filename is entirely displayed despite its length, what makes long texts overlap icons below. The only way to truncate the filename again
    is selecting another file (clicking on empty space doesn't work).

    The problem only occurs on desktop, no problem inside folders.

    My Windows version is 1909 (build 183363.778)

    Windows 11 Filename truncation

    Select only files that have "Copy" in the filename?
