Want to automate the rename procedure to prevent your files from being deleted?
If you use Flash FXP (and who doesn't) let the tool automate the procedure for you.
This is done by creating a custom command.
1) Select the Commands menu item
2) Press Add Cmd and add the Rename command
3) Paste the following text into the window:
RNTO %f ./ /
4) Click OK
After you've uploaded your files, select each one, click on the context menu (right mouse button) and select your custom Rename command. And you're done.
