A .arj extension file is a file that is compressed using the ARJ archiver. The program was developed by Robert K. Jung and hence the extension .arj stands for Archived by Robert Jung. ARJ was initially developed in 1990 for DOS and for the earlier versions of Windows. It was a very popular format for compression in the early days because it was very efficient at file compression. It was highly popular at the time of early networks. It is fast, reliable and helps to save on disk space.
The .gz filename extension refers to the GZIP file format and compression/decompression utility of the same name which was initially released in 1992. It is the extension given to files compressed using the gzip utility. Unlike other compression tools of the time, gzip was originally intended to be used as a tool to compress a single file as opposed to multiple files or entire directories compressed as a single archive. As a work around, multiple files can be archived using the TAR archive file format, then that single TAR archive would then be compressed using the GZIP format. This would give the file a filename extension of .tar.gz.
FreeFileConvert uses tuned encoding for ARJ to TGZ conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload ARJ files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized TGZ results on any device you rely on.
Process up to 5 files sized 1000 MB per batch without splitting queues manually. Mixed-format uploads convert together, producing consistent TGZ audio with dependable progress tracking.
The .arj file format supports data integrity protection, multiple volume archives, file version management, long file names acceptability, configurable options for commands and ANSI based escape sequence for display handling. This format is used to create high-efficiency archives of compressed files. The .arj file extension has advanced features which made it easy to split up a single archive into small chunks.
The GZIP format uses the DEFLATE algorithm for compression. A file in this format consists of a 10 byte header containing the version number, timestamp, and magic number. Other blocks include optional extra header blocks, the DEFLATE payload, and a CRC-32 checksum contained in an 8 byte footer.
Upload your archive file in the ARJ format from your device, Dropbox, or Google Drive.
Select TGZ as the output format and click Convert. Adjust optional settings if needed.
Download the converted archive file. Each file stays available for up to 5 downloads.
