GZipCompression

Multi-thread console program which is used to compress/decompress files using block-by-block compression. I've done this project as an entrance test for Software developer position in Veeam Software

Features:

• Compression by separate 1MB blocks
• Decompression
• Can decompress only those archives which have been compressed by the archiver
• Archives cannot be unpacked with other archivers
• Very fast (see "Test results" below)

Usage

1. Unzip package
2. Open Command prompt (or PowerShell)
3. Navigate to program's folder (cd "{ABSOLUTE_FOLDER_PATH}")
4. Type GZipTest.exe [compress | decompress] {ABSOLUTE_SOURCE_FILE_PATH} {ABSOLUTE_DESTINATION_FILE_PATH}
5. Press Enter
