I want to read a file name so that I can open and edit it.In terbo C, i was using findfirst and findnext.But with DEV C++ these function are not helping me.Is there any other function to get filename in DEV c++(C langauge function).

yes
files are going to be in perticular fixed location

I do not understand your problem.. Do you need the path to your file?

Suppose there are 10 ".txt" files in folder c:\trial.
I need to rename these files, new name is inside that file.
Now to open these files using file function fopen, I need program to read filename first so that I can look into file further for new name.

In terbo C ,function findfirst was giving me file name in structure variable ffblk.name.see below command
"done = _dos_findfirst("C:/trial/*.*",_A_NORMAL,&ffblk);"
Now I suppose to use dev C++, and for same function it is giving error.
Is there any other way to read file name.

I WANT TO AVOID MANUAL ENTRY FOR OLD AND NEW FILE NAME

So you want a search function. I see. Are you under windows?

yes

Check out the FindFirstFile() and FindNextFile() (and FindClose()) API functions. Here is an example (although using C++). I'll try to find one using C as well, if you need it. Windows SDK File System: How to search for files in a directory and subdirectories? - CodeGuru Forums

Some resources:

MSDN documentation:
FindNextFile Function (Windows)
FindClose Function (Windows)
FindFirstFile Function (Windows)
FindFirstFileEx Function (Windows)
GetFileAttributes Function (Windows)
SetFileAttributes Function (Windows)

Example from MSDN:
Listing the Files in a Directory (Windows)

A tutorial in C:
