The following data files and registry entries are maintained by PDQ Inventory. They are not removed on uninstall, in case the software is to be reinstalled. When moving to another computer these are the items that you will want to take in order to fully duplicate the system.
The database is stored in "%ProgramData%\Admin Arsenal\PDQ Inventory" and is made up of the following files.
%ProgramData% is a special Windows folder designed to hold application-wide (that is, not user-specific) data. The folder is marked "hidden" so you won't see it by default. Its location will vary depending on the version of Windows but is usually either "C:\ProgramData" or "C:\Documents and Settings\All Users\Application Data" and there is usually (but not always) an environment variable pointing to it.
Backup Database Files
Each time the database is updated for a new version of the software a backup is created in the Backups folder under the database directory above. The databases are compressed and are named with the version of the database that was being backed up. For example, in the "%ProgramData%\Admin Arsenal\PDQ Inventory\Backups" you might find Database.220.127.116.11.db.gz and Database.18.104.22.168.db.gz.
Older backup files can be safely deleted, but you may want to keep the most recent backups in case you want to restore.
To restore to a backup you need to decompress the file (most compression utilities, such as WinZip and 7-Zip can decompress it) and then rename it to Database.db and overwrite the database file. You will need to delete the Database.db-shm and Database.db-wal temporary files or else the file will appear to be corrupt to PDQ Inventory.
PDQ Inventory makes use of a number of temporary files which will always be stored in either the system temp directory (files used by the PDQInventory service) or user temp directory (files used by the console).
System Registry Keys
The following keys and values are maintained under HKEY_LOCAL_MACHINE.
User Registry Keys
The following keys are maintained under HKEY_CURRENT_USER for each user that uses the software.
