What happens to your file
The TAR archive is extracted into a temporary working directory and repacked as ZST. Everything happens in a directory that is removed afterwards even if the job crashes, so nothing is left behind on the server.
Settings this conversion runs with
| Source family | Multi-file archive |
|---|---|
| Target family | Single-file compression |
| Contents | Byte-identical after repacking |
What changes
- ZST wraps exactly one file — it has no concept of a directory or of multiple entries. If the TAR contains more than one file the job stops with a clear error rather than silently dropping the rest.
- Every file is fully decompressed and recompressed, so the contents are byte-identical but the archive size will change with the new algorithm.
