02 / what you get
What happens to your data
Kept
- Folders (including empty ones) and file names in any language, such as Cyrillic or Polish, are kept
- File dates and Unix permissions are kept, so a script that was executable stays executable
- Tight LZMA2 compression, usually the smallest result of all archive formats here
Good to know
- Windows and macOS cannot open 7Z by themselves. The receiver needs 7-Zip, Keka or similar software.
- Big archives take noticeably longer to pack as 7Z than as ZIP or TAR.GZ.
- The TAR was uncompressed, so the 7Z will be far smaller.
- Links (shortcuts) and special files inside the archive are left out. Only real files and folders are converted.
- Archives up to 300 MB are accepted. An archive that unpacks to more than 500 MB or 20,000 files is refused.

TAR vs 7Z
TAR
A TAR file bundles multiple files into one archive without compressing them (the name stands for Tape Archive). It's the standard way to package files on Linux/Unix systems, often combined with gzip compression afterward.
Used in: Linux/Unix file packaging · Docker build contexts · Backup tools
7Z
A 7Z file is the archive format of the 7-Zip tool. It usually compresses tighter than ZIP, which makes it popular for large downloads and backups, but Windows and macOS can't open it without extra software.
Used in: Large downloads · Backups · Game mods & software
