Strange. How long is this file name? NTFS file path maximum is 32K. I highly doubt your file path is that long.
More than likely you are talking about the 260 path limit in the console. You can get around that by changing your working directory(cd) part of the way to your destination. Then doing another cd.

(1)What do you mean by "NTFS file path maximum is 32K"? I mean the length of a path name has >limit in Windows.
NTFS is the file system Windows primarily uses. The file system allows file path lengths to be 32K, as in 32,000-ish characters. So I'm assuming you are running into the 255 file limit, which is kinda rare these days. Unless your programs are using the older APIs. To solve this issue, you have to be more specific with your problem. What program spits out the error and when?
(2)Can you say more about how "changing your working directory(cd) part of the way to your >destination. Then doing another cd"exactly is? I don't know how to do it.
cd is the command to change the working directory. Typically I ran into the 260 max path with batch files or console programs. You can work around the problem by using cd to change the current directory closer to your target.
For example, if you are targeting a folder under *\A\Really\Friggin\Long\and\Pain\in\the\butt\folder\in\a\path\this\long\for\some\acursed\reason\and\now\I\am\tired\of\this\insanity*
then you can type cd \A\Really\Friggin\Long\and\Pain\in\the\butt\folder\ and cut the path short enough to work with.
Again, this may have nothing to do with your problem since we have no idea what "programs" can't access these paths.
