The default location for PCb123 is:
C:\Program Files\Sunstone Circuits\PCB123 V4
PCB123 uses a different location to store User Files. I will only review the commonly used folders and their contents. If you have additional questions please contact customer support. Your libraries, designs, backup files, board templates, user preferences, and PCB123 start up files can be found in one of the following locations.
XP: C:\Documents and Settings\All Users\Application Data\PCB123
Vista and Win 7: C:\ProgramData\PCB123
Please note this folder is made invisble by default in Windows Vista/7.
BackupFiles – Contains the PCB123 created auto backups. PCB123 automatically creates a backup every 10 minutes. The backups are labeled the filename_Backup1.123, filename_Backup2.123, filename_Backup3.123. PCB123 stores 5 backups then begins to overwrite the backups after an hour.
BoardTemplates – The board outline templates that you see in the new board wizard can be found here. These are commonly used standard board templates which you can use, modify and share with other users. Any template that you create is also stored in this folder. To share a template you can email the template (.xml)file from this folder to another PCB123 user. All of the board outline edits and part placements will be saved in the template.
Designs – The default storage location for PCB123 design files. Unless you specify an alternate location when you save your files you will find you .123 files here.
