does Google drive delete your files?

Read their user agreement, and keep a local backup anyway, just in case.

Personally, I think all this "cloud computing" stuff is highly suspect. For example, I have a bunch of games that I purchased that are stored on Direct2Drive.com. I'm told I can download my games any time I want. OK, so my computer crashes, and I install a new hard drive, and now I want to download Civilization III. Guess what? IT AIN'T THERE NO MORE.

WTF??

Yah, I know it's an "old" game, but I still enjoy it. I TRUSTED these people and they let me down. I'm sorry, give me a local copy of everything. Disk space is not infinite, it's not free, and you never know when they might need to economize at your expense.

Google's agreement TODAY might be to keep your stuff for N years, and N years later you find out (too late) that they shrank it to N/2 years to save money. (of course they notified you of the change, but you weren't logged in for all that time, how would you find out?)

Keep a local backup.

No I don't think they will. Besides google drive hasn't been out for 2 years. But- read the end user license agreement to be sure.

it would want to bypass to the recycling bin of the computer that you deleted it on. so bypass back to the computer the position you got rid of it from the flash pressure and look there. in case you deleted it a at the same time as contained in the previous, some recycling packing containers empty out after some days or some different person might want to have emptied your recycling bin.
