File Compression and Decompression with FastLZ

This C program provides functionality for compressing and decompressing files using the FastLZ compression algorithm. The program supports multithreaded compression and decompression to utilize multiple CPU cores effectively.

Features

Compression: Compress single or multiple files into a compressed format using FastLZ.
Decompression: Decompress previously compressed files to retrieve the original content.
Multithreading: Utilizes OpenMP for parallelizing compression and decompression tasks across multiple CPU cores.
Dynamic Memory Management: Efficiently manages memory allocation and deallocation for handling large files.

Requirements

C Compiler
OpenMP library
FastLZ library

Usage

Compression

To compress a file or multiple files, follow these steps:

Compile the program using a C compiler.
Run the compiled executable.
Choose the compression option.
Input the name of the file(s) you want to compress.
Input the name for the compressed file(s).

Decompression

To decompress previously compressed files, follow these steps:

Compile the program using a C compiler.
Run the compiled executable.
Choose the decompression option.
Input the name of the compressed file(s).
Input the name for the decompressed file(s).

Example

$ ./file_compressor
What do you want to do? (1 - Compression, 2 - Decompression, any other key to exit)
> 1
Input name of file:
> input_file.txt
Input name of file you want to save as:
> compressed_file

$ ./file_compressor
What do you want to do? (1 - Compression, 2 - Decompression, any other key to exit)
> 2
Input name of file:
> compressed_file
Input name of file you want to save as:
> decompressed_file.txt
