Are you looking for the trunking data, decode logs or the activity logs?
Here's how to find all three ...
When the program starts, it reads basic configuration from a file named "Configure.xml". It looks for this file in the current directory - which is usually the same folder as the Uniform.exe program file. If you've created a shortcut - you can change the default directory to a different folder.
Included in the configuration data is the directory of where to find the system data and logs. You can see and optionally change this by selecting the Options tab from the main program window. It's the near the bottom. Look for a field named "Path" under the Unitrunker section. It is usually a period or dot which means "this" directory (the same as the shortcut or executable folder). You can change it to a different folder (eg. a USB drive for example).
In that directory you will find a series of files named "Unitrunker.xml". Most will include a sequential number. One of the files will not - that's the current, working copy of your trunking data.
You have two options for logging - activity logs - which are on a per-site basis and decode logs - which are on a per-receiver basis. The decode logs for each receiver are placed in a folder that starts with the letter "R" and an eight digit number. The log files accumulate and the roll on a daily basis. The files are named "Unitrunker-YYYYMMDD.log". Older logs may be compressed, in which case they will end with the letter "Z". To see the folder contents for a given receiver, open the Receiver window and click the folder button on the toolbar.
Activity logs are kept in a similar manner. The folder names start with the letter "S" and a serial number. To see the folder for a given site, open the site window and click the folder button on the toolbar.
For system data - you don't need to use Windows Explorer to delete the data. You can do so through the program. Select the system(s) you no longer want and click the delete button. It looks like a minus sign. I suggest doing this while the decoding receivers are off.
