My old phone was nearing its end of life so I bought a replacement. It has taken days to configure it to my preferences. Why does every App designer know better than I do what I want?
My new phone supports USB OTG (USB On The Go). All you need is a USB OTG cable like the (black) one shown in the (dreadful) photo and a USB hub with a card reader. That's a three port USB and SD/Micro SD card reader I normally use on my PC. There are much lighter ones on the market it just happens to be the one I have. In the photo it has two 128GB flash drive plugged in and an SD card.
All you then need is a file manager App to allow you to navigate around and copy files. A scan of Play Store threw up a host of them. Alas all were written by avaricious morons who knew only how to overload them with Adds while giving them the ability to copy only one file at a time. None of them would copy a folder (or its entire contents).
No problem I thought - I'll write one while we are waiting to get broadband at our new home. Fate conspired against me again - Tuesday morning my system hard drive was dead; I had an ISO of Windows 10 and plenty of backups for essential things. It still took two days to resume normal service. Except the Windows ISO resulted in 750MB of updates that swallowed my phone's hot spot data allowance. Andriod Studio was not among my backups. When I loose a system I find it far better to download the latest version of a program rather than load an old one and wait for all the mods to catch up. To add to my woes the roll-out of the NBN to our area has been delayed from October to January (at the earliest). So it may be a while before I can program anything. In the mean time if anyone thinks this photo backup idea has any merit please let me know what features you would like to see in such an App. All input a the early design stage will be most welcome.
My initial idea is to find or nominate the DCIM folder on the SD card and then use a systematic naming convention to create folders for each photo date and to copy the contents to both USB flash drives. With the usual options to skip or create copies of duplicates; I don't always delete the contents of my SD card after a days shooting. The will be no Adds or Malware in my App - if I ever get it going I'll post it here for those who might like to give this idea a go.
Dicky.
