        I use Borg backup  to save somes files on a network samba share.
        It's a backup program writen in python 3, who work on unix platforms. I=
        t run fine on cygwin.

        I have a bug on cygwin 32bit version only (on 32bit windows 7 computer)=
        , this not happen on 64bit version

        I mount the nas smb share with :
        net use W: \\\backup
        It's a smb version 1.0 protocol.

        When Borg try to write the index file on smb share it fail with [Errno =
        27] File too large error
        I tested with cygwin 64 and ubuntu 32&64 version on the same samba serv=
        er and no error happen

        An issue is open on borgbackup repo with some trace of the error


    How big is the file ?

the cygcheck.out does not report  a cygwin installation but a
msys one in "C:\Program Files\Git"

Where is your Cygwin system ?
Have you run cygcheck in the proper place ?
