Copy Handler: free software to copy and move files

Usually you can try to play with the buffer size (task properties or options) - it is up to you how to do it, because there is no official guide. In the future, manual buffer size settings will be replaced with automatic ones.

There is one more tip - if you are an owner of Windows XP 64-bit or later, or Vista 32-bit or later, you could try to:

• change the Copy Handler option "Disable buffering for large files" to "No". It defaults to "Yes", which works better on older systems.
• change option "Use only default buffer" to "Yes",
• change option "Default buffer size" to a lower value (512kB? 256kB? You need to experiment with it).

Note that it's not recommended to change those values for Windows XP 32-bit or earlier, because of expected performance issues.
