- The queried allocation unit is the smallest storage amount Windows can assign to a file; 4096 bytes is usually the default.
- Modern SSDs internally store data in pages and blocks, but emulate logical sectors through LBA for compatibility.
- The decades-old structure remained because it preserves compatibility and, according to the article, does not change everyday drive use.

- Since October 2024, Windows 11 24H2 has enabled Device Encryption by default on many clean installs and resets.
- For local accounts, Microsoft says the recovery key is not automatically saved when the device is encrypted.
- BIOS or UEFI updates, TPM changes, and boot-manager modifications can reportedly trigger the 48-digit key prompt.
- Users should save the key before changing Secure Boot or the TPM and suspend BitLocker during those changes.
I've argued time and again that many of the default settings and updates that Windows 11 ships with assume the best interests of the user, but in practice, they can backfire and cause them genuine harm and loss.— Abhinav, author of the article

- WizTree instead reads the Master File Table (MFT), which records filenames, sizes, physical locations, and timestamps.
- As a result, a scan typically takes only two to three seconds even with millions of files.
- SquirrelDisk needed about seven seconds for the C: drive, while WizTree completed the same scan in 0.9 seconds.
