The following GZIP-format compressed files can be imported by using the adbimport command:

Compressed input data files are imported by using the same method as for uncompressed input data files. Data can be imported by executing the adbimport command in which the absolute path to the storage location of the compressed input data file is specified for the input data path file.

Important

Only GZIP can be used as the compression format of input data files. Input data files compressed in other formats cannot be imported.

When importing input data files compressed in formats other than GZIP format, decompress the compressed input data files before importing them.
