bIn the System Properties dialog, click the Advanced tab, then click Environment Variables.

cIn the System Variables list at the bottom of the dialog, locate the following variables and adjust the values if needed.

DECOMP_LOG_FSPEC: the path and file name of the decompression service log file. The administrative user must have write-permission for this file. The format of this name must follow the usual pattern: <drive:>\<path>\<filename>.<ext> (neither <filename> nor <ext> may contain a period).

DECOMP_LOG_FILE_MBYTES: the maximum size permitted for the decompression service log-file (default is 1MB); when this limit is reached, the old log-file is renamed and a new one is created. The last 10 files are retained.

DECOMP_WATCH_DIR: the root-directory of the directory tree that will be monitored by the decompression service (default is c:\). This value should be changed to reflect the folder that is receiving compressed images.

The format of this name must follow the usual pattern: <drive:>\<path>[\]

DECOMP_DELAY_MS: the number of milliseconds that the service will wait after detecting a compressed file before beginning the decompression process (default is 50ms).
