    Why are Microsoft Apps and Services creating long path lengths?


    I first became aware of long path lengths exceeding MAX_PATH 260 characters, because my Windows 10 backup attempts are failing.


    I wrote a C++ app to scan my drive, looking for file and directory paths exceeding 260 characters.


    The app reported over 200 items, most paths are about 269 characters!

    Typical long path length folder is: C:\\Windows\servicing\LCU\Package_for_RollupFix~3...


    Is there any way to prevent, repair, these long paths?


    Any recommendations for resilient Backup software to backup my Windows 10 image?

    :)

  2. Long Path Names


    I forgot the other item on my "Wish List", long path name support (the default path name length is ridiculously short).

    Regarding panes and tabs, I use FreeCommander whenever I have to something more than basic file management.

    It has a handy mass rename tool too.

  3. Path length limit

    Hello John,

    My name is Patricia and I am an Independent Advisor. I am here to help you today.

    Disable the path limit length is recommended after Python setup is successful, because if python was installed in a directory with a path length greater than 260 characters, adding it to the path could fail.

    So don't worry about that action and proceed to it.

    Microsoft Removes 260 Characters Path Length Limit in Windows 10 RS


    Not necessarily a good thing. You will be able to create longer path names now. Programs that check path length will now choke on the long path names but would work fine with a shorter path name. Is that good or bad? Worse, a program that just assumes max 260 length might copy the name without checking and possibly overlay something. (I don't actually know if that is possible.)
