Windows encrypt folder: Some files not encrypted

Question

I did following two things to encrypt all the content of a root folder named "Foo":

The "Foo" folder has many levels of sub-directories with each having multiple files. All of the files in Foo were supposed to be encrypted, but some problem occurred and now only some files are encrypted. Others remain not-encrypted.

The only thing I can do is hunt down these files and encrypt them individually, but that would take forever. The "encrypted" attribute is set on the Foo folder itself, so I cannot ask the system to encrypt it again!

I want to encrypt all the files which are left out. How do I do it?

Answer 1

It may take a period of time to complete all encryption, based on sub files and folders size. If you can manually encrypt the sub folder with no problem, there may be some factors that disrupts the process(folder/file indexing).

Please try below suggestions to narrow down:

1. Please confirm that if same problem can be re-produces on same and different folders.

2. Re-start the system in Clean Boot(with 3rd party process disabled), open "Foo" folder’s properties – Advanced Attributes – Encrypt contents to secure data, then, check the result.

3. Open "Foo" folder, press Ctrl + A to select all sub folders and files, right click to open Properties – Advanced Attributes – Encrypt contents to secure data, then, check the result.
