What is Reddit's opinion of Zarchiver?

From 3.5 billion Reddit comments

I suppose you could also locally encrypt your sensitive files (if you still want to use SkyDrive). Just make sure you use a format that's compatible with your Android (as I see in the pic) too, for example you can use 7-zip to encrypt your files (and also compress them) using an AES algorithm, then if you want to see the content of your files on your Android, use ZArchiver.

uygulama kurmana gerek yok şu site baya iyi: https://www.compress2go.com/

illa uygulama istiyorsan : https://play.google.com/store/apps/details?id=ru.zdevs.zarchiver

ama uygulama, site kadar boyutu küçültmüyor haberin olsun.

A couple ideas:

Use ZArchiver to create zips of his photos. You could then transfer batches of photos in each individual zip file.

Install ES File Explorer on his older phone. Go to the Cloud tab and add one of your friend's cloud storage accounts - Dropbox, Google Drive, OneDrive, Box, and a few others are supported. You can use ES to copy folders to the cloud. Any file in a folder you copy is automatically uploaded. Once all the folders with photos he wants are backed up, you can install ES to his new phone and add the same cloud storage account you already used. Now you can use ES to copy those folders to the new phone.

You can! It's a .rar or .zip file. You can open those with another (free!) application on Google Play. I use ZArchiver. It works like 7Zip or WinRar.

Just extract somewhere on your phone and then you can install the .apk!

If you have the Google Drive app on your phone, you can save the .zip file from Gmail, use a file explorer app (I like ZArchiver) to upload the zip file to your Google Drive account, and then find the link to the file to share with us.

Or, if you're able to forward the file to my email, I can upload & share it for you. Let me know if you figure it out or need any help! :)
