I am using d=dir(*.001), and can see file name (abcd.001) from name=d.name but fid1=fopen(name) returns negative value.

I assume you meant to type d=dir('*.001') with the single quotes? Works for me PCWIN R2011a:
>> d=dir('*.001')
d =
name: 'abcd.001'
date: '24-May-2017 09:00:35'
bytes: 16
isdir: 0
datenum: 7.3684e+005
>> d.name
ans =
abcd.001
>> fid = fopen(d.name)
fid =
3

fopen replies -1, if the name is a folder.

Call fopen with two outputs. If the first output is -1, display the second output to see why the file open operation did not succeed.
