SparseChecker

Analyzes files and estimates the possible free space after making file Sparse. Frees the disk space potentially occupied by the continuous ranges of zero bytes in the file. Is especially efficient while processing Virtual Disk image files, preallocated database files, memory and other file produced by visualization software, download managers which preallocate the disk space for download tasks that are in Progress. From the perspective of other applications the file is unchanged after marked as a sparse file.
