Ensure there are no edits performed on the geodatabase folder anywhere else except within ArcGIS applications. Esri recommends making backup copies of the geodatabase to counter file corruption.
If the geodatabase contains a wrong extension, for example, .GDB instead of .gdb, rename the file geodatabase folder extension with the steps provided below.
Note: Ensure the geodatabase folder data is not accessed by any other client, simultaneously, during this operation.
