1. Use rsync to copy the project data from the old disk to the new disk.  For example, if you wish to move Project A from an internal disk to an external drive mounted as hdd: 

   $ rsync -avr /home/user/FlowData/Project_A /mnt/HDD/FlowData2/Project_A

   Using rsync -avr guarantees that the time stamps would not change.
    

2. In Partek Flow, logon as a user with Admin privileges. Go to Settings>Directory permissions page
   
   
3. In the Directory Reassignment section, type the Former directory and select the Current directory (Figure 1)
   
   For example: 
   • • Former directory: /home/user/FlowData/Project_A
     • Current directory: /mnt/HDD/FlowData2/Project_A

5. Open the project. 
   
   
   • • In the Analyses tab, check if the Project disk space on the lower right has been updated
     • In the Data tab, check the project output directory has changed to the new directory
        
6. You can now remove the former directory
