QGIS Browser Setting#

If QGIS freezes when opened, there is a potential fix in the qgis.ini file. This simple fix will stop QGIS from trying to read locked drives.

The file is found here: C:\Users\ACCT NAME\AppData\Roaming\QGIS\QGIS3\profiles\default\QGIS

  1. Open the file from the QGIS profile path.

Project Path Changes#

Path corrections may be required if the project folder was changed or moved to a new computer. External data links can be correct using number 1 below and the geopackage links are automatically corrected by the Plugin as shown in number 3 below.

Important Note: If the ProjectName.gpkg file is still in the old path, it will be chosen automatically.

  1. Fix the links with QGIS and the FLO-2D Plugin with this process.

  2. Fix the external data links with the Handle Unavailable Layers window. Auto find works well. Apply Changes to close the window.
