What would I type in for adb to install an apk from a specific file path on my computer?

i know but how do i do it manually?

YEG navigate to the apk in file manager and then copy it from the address bar.

you might have to type "cd" and space before

YEG On WebADB you can select the file that you want.

practical before the apk or before the path? And can you write out the whole command please? Thank you for your help!

YEG On the left side of the screen simply click install apk then you can select the apk that you want.
Have you ever used webADB before?

TryingToBeHelpful basically I have a Android tablet with an adb app which connects through otg. The only way I can install apps is writing out the whole command including the path. But I don't know how to do that. Can someone help me?

YEG Did you try running WebADB on the tablet?

lgexalter1 where does pm install -g go?

lgexalter1 do I have to write cd anywhere in command?

YEG sorry for delay... i'm not sure in your case but you can give it a try.. so it's to type before the path like:
"cd C:\Users\PRACTICAL\Pictures\Saved Pictures" or it could be:
"cd \Users\PRACTICAL\Pictures\Saved Pictures"

lgexalter1

YEG it's usually storage/emulated/0/whatever....
