You can also switch to partition mode where you can scan for files and file lengths. Select the partition of interest from the drop-down list. You specify the initial directory where the search starts. There is also an option “Search in sub directories recursively”, if you don’t know the exact place of the file. This way you can search complete partitions if needed, but be careful, each entry will do the search which can consume a lot of scan time.
The more adequate you provide the initial directory the faster will be the scan.
