Haan 👍 ye command time leti hai — aur ye normal baat hai.
Main simple shabdon me samjhaata hoon 👇

⏱️ Time kyun lagta hai?

Ye command:

Har folder ke andar

Har sub-folder

Har file ka size
check karti hai

Isliye ye complete scan karti hai.

⏳ Kitna time lag sakta hai?

Depends karta hai:

Disk ka size (HDD / SSD)

Files ki quantity

Folder depth

Approx time:

SSD → 2–5 minutes

HDD → 5–15 minutes

Bahut zyada files → 20 minutes tak

➡️ PowerShell freeze nahi hota, bas background me kaam karta hai.
