Find current file
Wherever you are on your drive, Runtime's DiskExplorer lets you determine to which file the current cluster belongs to.
Set the cursor to the data area you are interested in, then click Tools->Find current file. If the cluster is associated with a file, after a while of searching a window will display the MFT number of the file, the file name and the attribute the data belongs to.
To go to the file entry just click Go there in this window.
