   - Enables on-the-fly compression format conversion during download. Supported formats: `bz2`, `gz`, `xz`. Downloaded files will be automatically decompressed and recompressed to the target format. Example: `--convert-to gz` converts all downloaded compressed files to gzip format.
 - `--convert-from`
   - Optional filter to specify which source compression format should be converted. Use with `--convert-to` to convert only files with a specific compression format. Example: `--convert-to gz --convert-from bz2` converts only `.bz2` files to `.gz`, leaving other formats unchanged.
+- `--validate-checksum`
+  - Validates the checksums of downloaded files against the checksums provided by the Databus. If a checksum does not match, an error is raised and the file is deleted.
