# PDMDataCache File Lock

### <mark style="color:blue;">Applies to</mark>

Regular Non-Collaboration projects.

### <mark style="color:blue;">Problem</mark>

With the release of PlantDataManager 7.3.0.3767 we introduced a late bug. This has the effect, that you cannot continue editing your changes if you try to open the project again in PlantDataManager.

### <mark style="color:blue;">Description</mark>

When you start making your first changes in PlantDataManager and you save your changes, PlantDataManager will not only save your changes in your personal PDMDataCache\_\[USERNAME].dcf file, but will also create a lock file to make sure your changes cannot be imported through PlantDataManager Plugin.

However, when closing the project in PlantDataManager the lock file wasn't removed.

The PlantDataManager Plugin will also show a dialog, that your file is locked.

### <mark style="color:blue;">Solution</mark>

Update PlantDataManager to version PlantDataManager 7.3.1.3787 or simply remove the lock file in File Explorer.
