Recover LZH files with Active@ UNDELETE
- History: The LZH format, created by Haruhiko Okumura in the 1980s, is a compression format commonly used in the Japanese computing community. LZH combines the Lempel-Ziv-Welch (LZW) compression algorithm with Huffman coding to achieve high compression ratios. It was popular in the early days of personal computing and before the emergence of widely used formats like ZIP. LZH files typically contain multiple compressed files and maintain the original directory structure.
- Active@ UNDELETE and File Signatures:Active@ UNDELETE's File Signatures feature actively identifies the signature markers of LZH files, allowing for efficient recovery of accidentally deleted or corrupted LZH archives. With its seamless scanning capability, Active@ UNDELETE ensures the retrieval of vital LZH files, preserving memories from bygone eras. To find and recover LZH files select lzh in the File Recovery Wizard menu.
Recover TAR files with Active@ UNDELETE
- History: The Tape Archive (TAR) format dates back to the early days of computing. Originally developed for storing files on magnetic tape, TAR became widely adopted in Unix-based systems as a method for bundling multiple files and preserving file attributes and directory structures. TAR files do not perform compression by themselves and are commonly compressed using other formats like GZ or BZ2 to create compressed TAR archives.
- Active@ UNDELETE and File Signatures:Active@ UNDELETE harnesses the power of its File Signatures feature to detect and recover deleted or damaged TAR archives. With Active@ UNDELETE, users can effortlessly restore their TAR files and extract the valuable data encapsulated within them. To find and recover TAR files check tar in the File Recovery Wizard menu.
Recover RAR files with Active@ UNDELETE
- History: RAR (Roshal Archive) format was created in the early 1990s by Eugene Roshal. RAR files employ a proprietary compression algorithm that offers high compression ratios and the ability to split archives into multiple smaller volumes. RAR gained popularity due to its strong encryption capabilities, recovery records to repair damaged archives, and support for storing file ownership and file attributes. However, it is a closed-source format, and the RAR archiver software is not freely available.
