While copying files from windows to Solaris5.8 with filezilla length of the filename changed

Hello
I am copying a tar from windows7 to Solaris with filezilla i could see, some characters in the name of the file get deleted.
I could see only substring of the filename
eg: original filename :abcdefghijklmnopqrstu.h
i can see like abcdefghijklm
solution to this problem is highly appreciated.
Thanks in advance

Maybe filezilla thinks the windows machine is 8.3 and truncates at 12 bytes? Is it the latest version?

Issue get solved ,when am copying .gz.tar issue came, I tried with .gz now no issue
