getting information on a file ENTRY

Will it be on a NTFS or FAT volume, file entry (of MFT record) properties can be easely decoded.

When possible, try locking the volume before, so helping Tyrhex by providing the volume essential settings.

Locate the desired file entry and set the position on the first byte of it (for NTFS, the first byte of the MFT record, usually at the start of a sector, for FAT the first byte of a 32 bytes entry). Use then the feature « Analyse - Item at sector » and you will get all information available for this item. When possible, navigation through the file system tree.

Keep upgrading your version, as we will implement more and more features to analyse other file systems and meta-data embedded in some file types.    

Rebuilding a deleted Volume

When the Volume Boot Sector is missing,  needed information about block (cluster) size, there is no way to recover the needed data.

Creating a « fake » volume using Tyrhex allows to specify the needed data in order to access to the files metadata (file name, date and times) and content. 

Recovering a file from A NTFS partition damaged after Quick format

When a quik format action is run on a NTFS volume, the previous MFT is overwrite by then new one .

As the volume size, location and the Operation System File Driver are the same as before, the newly created MFT is saved from the same cluster (block) as the previous one. However, a fresh new MFT includes only a few records, some used for the system files, others free and available. Consequence is that lot of the previous MFT file, containing records from the system before the quick format, are still recoverable.

Going on the MFT bookmark for this volume, the cursor will then allow to get file size for the first MFT record (record 0 -> MFT file).  Using this bookmark as locked reference, a simple Tyrhex jump will locate the cursor on the last byte of this file. 

Next step is to look after this position. You will find there former MFT records still available but in the unallocated space (new MFT « reserved »  space for future growth avoiding MFT fragmentation). All files records discovered in this unallocated space are easy to decode using Tyrhex.

Last step is to ask to recover the clusters … Tyrhex will allow you to save the file content.

exFAT deleted files, even fragmented, are recoverable … looks how you can use Tyrhex to do it :)
