Asynchronously Sync dir consumes memory when deleting

[GreenManHunter]

On my W7 I synchronize c:\users to an external HD as backup.
I compare asynchronously and synchronize.
On the last synchronization I had a large number of files on the right to be deleted (21000 files out of 210000).
After deleting some thousand files Total Commander (TC) goes slow and the pc goes slow.
I stopped TC and started it again monitoring the memory usage.
TC consumed a little memory during comparison.
Under the deletion TC consumed a lot of memory.
After deleting 5000 files TC used over 1.5 GB of memory and I had to stop TC before my PC was slowed totally down.
Before I had deleted all the files, I had to restart the TC 5-6 times.

My TC version is 8.0 64 bit (2012-05-23)

Normal deletion at synchronization will delete to the recycle bin.
With this huge amount of files the recycle bin will easily reach the limit of capacity.
This will at least slow down the whole deletion process.
Don't know about memory consumption.

To avoid the usage of the recycle bin, just press the SHIFT key when clicking at dialog "Are you sure to delete xxx files" or alike.

BTW: You should update TC to 8.01

Thanks for the hint about the SHIFT key.
I also updated TC to the newest version and tried a sync again.
I deleted over 50000 files in a fraction of the earlyer times
And there was NO memory problems.

In newer versions, TC deletes one directory at a time to recycle bin. In older versions, it deleted each file separately. This is a problem because Windows Vista or newer creates a new thread for each delete operation (to recycle bin). Unfortunately it's not possible to pass all files to the delete function, because it then starts deleting the wrong files(!).
