Clicking on Abort when a large file transfer cause problems

[inbalziv]

When user click on Abort in the middle of transferring a large file:

1. Takes too much time till the Run appears (it appears only when the large file finished to transfer)
2. The view is slow, when clicking on folders it loads empty

To solve it:

1. When clicking on Abort --> window should pops up and ask the user if he sure he want to abort
2. User click on yes in the pop up window --> a window appears with "aborting.." message till the file finish to transfer
