Switch -AS - synchronize archive contents


If this switch is used when archiving, those archived files which are not present in the list of the currently added files, will be deleted from the archive. It is convenient to use this switch in combination with -u to synchronize contents of an archive and an archiving folder.

For example, after the command:

WinRAR a -u -as backup sources\*.cpp

the archive backup.rar will contain only *.cpp files from folder sources, all other files will be deleted from the archive. It looks similar to creating a new archive, but with one important exception: if no files are modified since the last backup, the operation is performed much faster than the creation of a new archive.

Available for RAR format only.
