BoxCryptor on Synology NAS shared volume

gmiki

I tray to use BoxCryptor on Synology NAS shared volume. Work well except than file size stored on encrypted folder become bigger.
It is strange because if I store a 9 bytes length TXT file for example, on the encrypted folder by BoxCryptor (on Synology shared volume) that file seems to be 16 bytes length. It is very frustrating because I cannot use any file compare method because of different file size. When I copy that bigger file to local folder (HDD for example) that file become again 9 bytes and is identical with the original. If I copy that original size file to Synology shared volume folder without BoxCryptor encryption, that file also remain 9 bytes length and identical with the local one.

Can someone help me with this problem?

Every encrypted file will be bigger in size (around + 4 bytes more) because of the encryption header.
If you save the encrypted file again on a location outside of the Boxcryptor drive, the file (the copy of your file) will be decrypted and so the size will decrease again.
Have a look here at the file (on a Synology share)

Thanks for response.
Unfortunately, something is different in my experience when I mounted with BoxCryptor one folder stored in Google Drive volume and another folder stored in Synology NAS.
Let see the image, in the left side is the file encrypted on Synology drive and in the right side the same file crypted on Google Drive, also the original (unencrypted files is like in right side).
I try the experiment with one 1-byte length file also with one 10-byte long file, the result is the same.
In the Google Drive is stored with original size, in the Synology drive is rounded up to 16-byte.
(if the original file size equal or more than 16-byte and less than 32-byte, the file size is rounded to 32-byte)
About the encryption, below is the real size of encrypted files stored on Synology (left) and Google (right).
I think the purpose of BoxCryptor mounted volume could be to show the original file, not any modification because of encryption. This is realized in case if the encrypted files is stored on Google Drive. I don’t know why not in case when the encrypted files is stored on Synology NAS.
