```
public class OtherByteAttributeMultipleCompressedFilesOnDisk
extends Attribute
```
A concrete class specializing Attribute for Other Byte (OB) attributes whose values are not memory resident but rather are stored in multiple compressed files on disk.

Whether or not decompression of compressed file format is supported is not checked until an attempt is made to write decompressed bytes.

Which decompressor to use is determined by the file name extension (.gz for gzip, .Z for unix compress, etc., case insensitive).
