Attachments management should improve
When I get a mail with a .zip or .csv attachment, even very small ones, Boxer seems unable to download the attachment (even with full wifi connection strength).
It tries "extracting" the csv which takes forever.
For a zip file, it says no application found to treat it even though I have ES File explorer and 7zip installed.
In general, it should be shown where a saved file was stored too
File handling is done by Android.
Downloading is handled by Android.
Files are always downloaded to the /download folder of your device.
1 tip: Always use the “download file” option ion the 3dot overflow menu on the attachment to download the file to your device, instead of just tapping the attachent on the bottom of the email message.
What account type (POP/IMAP/Exchange) are you having this issue with?
I can suggest you with the "Cloudbacko software" actually it can give backup to your photos and videos and with backup you can take backup and with that it helps in restoring also, and you actually try many more other softwares in the market.
