I've noticed BitTorrent Sync appears to fragment my hard drive pretty badly.
2 Laptops (Laptop A and Laptop B), both with 500 GB hard-disk (5400 RPM disk)
Laptop A has Windows 7, various programs, and 4 30+ GB folders (each with 10,000+ files)
Laptop B has Windows 7, few programs, and few files
Steps to reproduce:
Step 1) Defragment both Laptops A & B
Step 2) Sync 1 30+ GB folder from Laptop A to Laptop B
Step 3) Check fragmentation of Laptop B.
It is now over 10%
If you repeat steps 2 & 3, then the fragmentation is over 20%.
Any ideas on what can be done to prevent this fragmentation?
