I've a little problem: I have to open a linker file that has .a extension. I use Dev-C++.

Decompressing a zipped file or folderFind the file you want to decompress, right-click it, and choose Extract All. In the dialog box that appears, to choose the destination for the decompressed files, click Browse.... You can also check the option Show extracted files when complete. Click Extract.
An A file contains a library of functions and headers that may be referenced by a C/C++ source file. It may store only a few functions or may include an entire library of functions, such as a 3D modeling engine. A files are typically created by the GNU ar utility.
. a files are static libraries typically generated by the archive tool. You usually include the header files associated with that static library and then link to the library when you are compiling.
.a files are ar archives (something like zip archives) of object (.o) files. You can list files in .a file using ar program:
ar t file.a
And extract all files:
ar x file.a
Files with the .a extension are static libraries using Unix file naming conventions. They're not much more than an indexed collection of object code. You don't so much open them (unless you've got a tool like nm or gdb available, both of which can do sensible things with a library if not necessarily what you might want) as tell the linker to use them when linking. With most linkers, it's important to put all libraries (both static and dynamic/shared) after your main program code on the linker command line and the order of libraries matters too.
