2.2.3.12
This command initiates a garbage collection. Until a garbage collection, files that are
marked for deletion still occupy the associated file descriptor and memory space. After
the garbage collection these file descriptors and the associated memory space are
available again. This command can optionally remap the directory. In this mode the
remaining file descriptors are remapped to form a contiguous block starting with file
number 1. The original order is preserved. This command requires that all files are
closed, i.e., file 0 is opened. Independently of the selected directory only the read/write
directory is used. The command can be aborted any time and resumed later on by
Data Sheet
to be a valid file.
