The UrvbaseJ/unravel/urtext directory will normally contain up to four distinct text files or file sets that are generated after the Unravel program has been run one or more times. For installed versions of the Unravel program, these files will not be removed by relevant uninstaller programs. Only the user can delete some or all of these files prior to installing any Unravel program update. The basis for the retention or deletion of these files when updates of the Unravel program are downloaded (either installed or uninstalled arrangements) is:
Macro definition files with "urvcmd" as the first part of the filename can all be regenerated by the program if default macros are used and in such cases can be deleted. Failure to delete them will prevent any program updates being reflected in any macro definition file that has a corresponding entry in the urtext directory.
Saved cube state files with "urvhld" as the first part of the filename can all be deleted unless the user is part way through solving a cube and has saved the partially unscrambled state. In that case only the relevant file needs to be retained.
The urvstart.ini file can be deleted if the user has adopted the default colour set. If the user has changed the colour set, the file should be retained as changing colours can be tricky and time-consuming.
If the user wishes to retain the cube solving time history, then the urvlog.txt file should not be deleted.
If none of the above files needs to be retained, the urtext directory (and all of its contents) can be deleted. The urtext directory will be reinstated when the program is next run. If just the urvlog.txt file is to be retained it can be copied to a temporary directory and then moved back to the urtext directory after the program is first run after an Unravel program update.
