Copying split apk file creates multiple files with tc 3.10b8.

This problem has existed for months, but I haven't had time to look into until now.
When copying a split apk (such as a chrome apk) with installed files plugin or tc multiple target files are created.
It appears that each apk file other than the base creates a separate file.

Cursory testing shows the files can be installed by either y-split or tc by putting all files into a zip file and instaalling from that.
Based on suggestions from y-split, I've been revnaming these zip files to apks.

with my phone, moto z4 Android 10, Solid Explorer seems to copy ok.
I can't install thar app on my ancient tablets, Verizon Ellipsis 10 Android 5.1, but the built in File Manager seems
to work ok.

P.S. All these activities took place on the sd card.

I see from "Split/Multipart Apk" that thereis a better way of installing the parts of a spli apk thanI've been doing.

However, I still think it would be useful to copy the entire source file That's what I would normally expect to see.

There isn't just one source file when you have split apks. There is a base apk plus several extensions. The base apk contains the main java code, and the extensions contain device-specific code and data:
1. Native code for ARM, X86, ARM-64 and X86-64 processors. Only the one for your specific processor will be installed
2. Resources like dialog boxes for your device size and Android version
3. Language files for your current device language

When you backup a split apk now, TC will backup ALL the parts present on your device. This is not a bug.
