Note that most Windows programs (including Windows Explorer) will not be
able to access files and directories whose paths exceed MAX_PATH, i.e.
260 characters (259 including null).

This means that the actual utility of copying such files to the machine
with a later version of Cygwin will probably be limited to manipulation
solely with Cygwin programs.

Details:

The Win32 NT subsystem can handle them, by using the \\?\ pseudo-UNC
syntax, but programs have to be written with that in mind. Most software
written in C & C++, and also many Windows-specific RTLs of other
languages, assume MAX_PATH to be the maximum file length and would
actually crash if forced to handle a file longer than MAX_PATH.

One way around the above issue would be to use a junction or similar to
shorten filenames for other programs.
