File-Level Encryption

Question

I am looking for a file-level encryption program that ideally runs in the right-click context. Previously I utilized AxCrypt, however this has gone to a premium subscription-model, requiring a $30.00 per year license to use AES-256!

Essentially I want file-level encryption (AES-256 as the preferred), that allows me to decrypt the file when used, and then encrypt when done. The reason I want this is the data will be encapsulated in a PGP disk with encryption, thus adding another layer of support. Therefore, tools like EncFS and Veracrypt (to my knowledge) fail - they are encryption disks/partitions that store non-file level encrypted files within them.

Presently, I am trialing AES Crypt, however already have the following issues:

1. It makes a duplicate encrypted file, meaning I must delete the old file once performed.
2. When decrypting the file, if the name exists (as in notes.txt) it will not replace that file.
3. Concerns with automation of the process as listed here.

I have also trialed crococryptFile and have noted the following issues:

1. Each time a file is decrypted it is placed inside a EncryptedFile folder;
2. Multiple files/folders are not supported to be encrypted at any one time and;
3. The GUI feels bloaty/slow, and is not a "fast" process to perform actions.

Requirements

1. Support AES-256
2. Be less than $30.00(Australian Dollar) for single purchase
3. Run on Windows 10 natively
4. Have the capability to encrypted multiple files at once

Nice to have:

1. Right click context menu
2. Command line options (for batch processing)
3. Replace files when encrypted (*.txt becomes *.encryption-file-type)
