encryption left to right, how to easily see files if browsin

[spagnola]

I encrypt files going left to right.
I know I have to decrypt them individually coming right to left, to restore. I use syncovery to do that.

BUT, this weekend, I wanted to take my encrypted-file-disk to another location, and be able to VIEW the files on that disk. in order to do so, I have to use something like 7-zip, etc, and paste the encryption key for each file.
does anyone know of any ZIP program that can RETAIN the encryption key, to open some sequential files, (until the system is restarted, cleared, etc) so that I CAN take the encrypted disk, yet be able to see the files using some program that allows such opening by retaining the encryption key?
