What happens when a file is deleted in Windows 7?

• A. The last letter of the file name is replaced by E5h hex
• B. The MFT entry is marked as deleted with a special indicator
• C. The clusters in the FAT are marked as used
• D. The system erases the file data immediately

Answer: (B)

When Windows 7 deletes a file, it uses the NTFS filesystem behavior: the file’s record in the Master File Table (MFT) is marked as no longer in use and given a deleted-indicator, rather than immediately wiping the data off the disk. The MFT entry is flagged as deleted, and the directory entry that pointed to the file is detached. The actual file data clusters on the disk aren’t erased right away; they’re simply marked as free space and can be overwritten later as new data is written. This is why deleted files can sometimes be recovered with forensic tools until the space is reused.

The other options don’t fit NTFS behavior. The 0xE5 marker belongs to FAT directory entries, not NTFS. The FAT table concept isn’t how NTFS tracks deletions. And deleting isn’t an immediate data erasure—the data remains until overwritten, which is why deletion isn’t a secure erase by default.
