In older Dynamics NAV versions (and obviously, working on Windows XP), I needed to delete ZUP files quite often. Now, when I think back, maybe too often… Anyway, C:\Documents and Settings\YourUsername\Application Data\ path (that’s where ZUP files were saved in Windows XP) has been rooted down into my memory for ever. However, recently I was asked how to delete the ZUP file for Dynamics NAV in Windows 7, and my default answer (Documents and Settings) did not work!
It took me a minute or two, to find where the ZUP file resides in Windows 7, and while I haven’t memorized it yet, it might be a good idea to write this down.
How to delete ZUP file in Dynamics NAV in Windows 7
Start “My Computer”. Go to C:\Users\. Find your username (in my instance, it is TomasZ) and go into that folder.
Now, do you see a folder called “AppData”? If not, don’t worry, the folder is hidden. Click ALT+T on your keyboard (this will open Tools menu) and select “Folder Options”.
Click on tab “View”, and find property “Hidden files and folders”. You will need to click on “Show hidden files, folders, and drives“, in order to see “AppData” folder. Click OK.
Result (now you can see the AppData folder)!
But the job isn’t done yet. We need to go into AppData folder, and then into Roaming folder. So, now you should be in C:\Users\USERNAME\AppData\Roaming\. You will find your ZUP files at the bottom of this folder.
Click on the fin.ZUP file and delete it. The next time you start Dynamics NAV, the program will create a new, clean fin.zup file.
