Abstract
A method and system for rapid data-fragmentation analysis of a New Technology File System (NTFS) is described. In one embodiment, the Master File Table (MFT) associated with a NTFS volume is analyzed to estimate the extent of data fragmentation on the NTFS volume, the analysis being performed substantially without using directory index information associated with the NTFS volume.
Claims17
A method, comprising:
- analyzing a Master File Table (MFT) associated with a New Technology File System (NTFS) volume to estimate the extent of data fragmentation on the NTFS volume as a whole, the analyzing being performed without using directory index information associated with the NTFS volume;
- wherein analyzing the MFT includes counting the number of data runs referenced in a data attribute of a record of the MFT, the data attribute including the number of clusters in each data run.
A system, comprising:
- an analysis module configured to analyze a Master File Table (MFT) associated with a New Technology File System (NTFS) volume to estimate the extent of data fragmentation on the NTFS volume as a whole, the analysis module being configured to analyze the MFT without using directory index information associated with the NTFS volume;
- wherein the analysis module, in analyzing the MFT, is configured to count the number of data runs referenced in a data attribute of a record of the MFT, the data attribute including the number of clusters in each data run.
A system, comprising:
- means for accessing a Master File Table (MFT) associated with a New Technology File System (NTFS) volume;
- and
- means for analyzing the MFT to estimate the extent of data fragmentation on the NTFS volume as a whole, the means for analyzing the MFT being configured to analyze the MFT without using directory index information associated with the NTFS volume;
- wherein the means for analyzing the MFT is configured to count the number of data runs referenced in a data attribute of a record of the MFT.
1 more element
A computer-readable storage medium containing program instructions, comprising:
- an analysis instruction segment configured to analyze a Master File Table (MFT) associated with a New Technology File System (NTFS) volume to estimate the extent of data fragmentation on the NTFS volume as a whole, the analysis instruction segment being configured to analyze the MFT without using directory index information associated with the NTFS volume;
- wherein the analysis instruction segment is configured to count the number of data runs referenced in a data attribute of a record of the MFT.
