The file preferences tab includes settings that affect the Paradigm LightDesigner configuration file.
When saving a LightDesigner project and the "Append job number and job revision to filename" is enabled, the filename will save in a format similar to "ABC Hotel - Ballrooms, 123456, rev1.pcf". The job number and job revision are appended only if they have been entered in the New Project Wizard or New Server Project Wizard when the project was created.
LightDesigner provides backup and autosave features for user convenience.
When "Autosave" is enabled a copy of the open configuration will be made based on the time interval specified. The number of backups specified will be kept at all times. Backup files are created with the same project name and appended with "bak_currentdate_currenttime" (for example "ABC Hotel - Ballrooms, 123456, rev1_bak_2012-12-20_15-15-16.pcf"). Manual save actions overwrite the oldest backup file when the user specified limit has been exceeded, and remove the autosave file until there has been unsaved edits for the specified time interval.
