Empty directories and 0 byte files are deleted from locked branches and ToSorts

Any branch or ToSort can be locked in the tree and is signified as such with a lock icon. This implies that the directory will not be modified and no files will be deleted. However, even if a directory like a ToSort is locked, 0-byte files and empty directories will be deleted during a fix.

This issue is problematic for some collectors who keep 0-byte files or directories in their archives that they want to keep. For example someone may create a 0-byte file placed in a directory that has a filename that indicates where they found the content. Also, many old PC games present in TDC and eXoDOS sets contain intentional empty directories.

Steps to reproduce:

1. Create a 0-byte file and place it in a non-Primary ToSort

2. Create an empty directory and place it in your non-Primary ToSort

3. Lock the ToSort directory in the tree

4. Scan the ToSort so that the file and directory are logged in RV's cache

5. Perform a fix while the ToSort is locked

6. Notice that the 0-byte file and empty directory are deleted

Expected behavior:

• 0-byte files and directories should not be deleted if the directory is locked as indicated in the tree
