It depends on the following factors:
- The size of your file. If your file is huge, then it will take a long time to analyze since our program will check and analyze every byte in your file, which is rather time-consuming. For example, a 100GB PST will usually take about 10+ hours to repair.
- The complexity of your file. If there are many data and they are cross-referenced by each other in your file, then usually it will take more time to repair it. For example, a SQL Server MDF file with a lot of tables, indexes, and other objects will normally take several hours to repair.
- The type of your file. Some file formats are especially complex, which require more time than others. For example, AutoCAD DWG file is rather complex, so even a 5MB DWG file may take several hours to repair.
