What is a TAR.7Z file?
A TAR.7Z file is a compound archive that first encapsulates files into a TAR container to preserve Unix file permissions and directory structures, followed by compression using the 7z format's LZMA or LZMA2 algorithm. This two-step process addresses the limitation of the 7z format, which does not inherently store Unix owner/group permissions, while leveraging 7-Zip's high compression ratios and solid compression capabilities. The resulting file requires decompression of the 7z layer followed by unpacking of the TAR stream.
How to open a TAR.7Z file
Opening this format requires a utility capable of handling the 7z compression algorithm. On Windows, 7-Zip is the primary tool for this specific dual-extension format. macOS users can utilize Keka or The Unarchiver, while Linux users typically employ the p7zip package via command line to first decompress the 7z layer, then extract the underlying TAR.
