SyncToy writes a file, "SyncToyDirectoryId.txt" in my directories!

NOOO! I hate this. I don't want useful tools writing their own files in MY
folders. Use another .ini file somewhere else, use the registry, but do NOT
write files into my folders - it's pure evil! :P

Is there any secret option or registry edit I can make to PREVENT SyncToy
from writing the SyncToyDirectoryId.txt files?

If not, there should be <--- that's my suggestion.

Thanks,
Bit.

You are right. They are your folders, and should be left alone.

I wonder about the experience level of the people who designed / programmed
SyncToy. They state that 55% of respondents wanted to be able to type in a
UNC path, so they added the feature. Duh?! You think so? How come they
could not come up with that on their own?

".. thanks to our feedback and focus groups, we discovered that users wanted
to software to perform it's basic function, so we added that feature.."

But they still did not get it right - there is no support for Web Folders
(webdav) in SyncToy that I can find. They actually put some effort and work
to defeat it, by not allowing me to type a forward slash in the location box.

If you *really* don't want those files, you could always use one of the
other synchronization tools out there (I used to use FileSync, for example).

However, you'll soon find out what you'll be missing. Those little ID files
let SyncToy track directories across renamings. And in my household, with 4
machines (sometimes 5) synchronizing folders and pictures from more than one
person, one of which (we'll leave names out of this) who likes to rename
folders, well...

Now, there really are SyncToy features to hate (the exclude folder dialog
isn't resizeable, dialogs get confused with non-default font sizes, a lack of
excluding files by extension, yada). I don't think this is one of them, once
you understand why the file is there and what it buys you.
