Hello,
I have a problem with the correct NTFS permission on the shared directory.
I would like to give "modify" permission on the directory without delete, but when I do this user can not save and copy files to the source directory.

In NTFS security on the directory, I try few combinations - I add 2 times the same group:
1. a) Read-only - on this folder only
b) Modify without Delete - on Subfolders and files only
2. a) On this folder only - Read-only with Delete subfolders and files
b) Modify without Delete - on Subfolders and files only
3. a) Modify without Delete but checked Delete subfolders and files - on this folder only
b)Modify without Delete - on subfolders and files only


Someone know how to this correct?
