If someone shares his Google Drive with me and in the future deletes a file in it, will that file be available to me in my Drive?

If someone shares a file or folder with you on Google Drive and they later delete that file, it will no longer be available to you in your Drive. Here are the key points to understand:

File Ownership

• When a file is shared with you, you do not own the file; the person who shared it with you does. Therefore, their actions on the file will affect your access to it24.

Deletion by Owner

• If the owner of the shared file deletes it, the file will be removed from your "Shared with me" section, and you will no longer be able to access it. The file will go into the owner's Trash, and if it is permanently deleted from there, it will be gone for everyone who had access to it13.

No Local Copy

• Removing a shared file from your "Shared with me" section only removes the link to the file from your view; it does not delete the file from the owner's account. However, if the owner deletes the file, you will not have any local copy of it unless you had previously made a copy of the file to your own Drive14.

In summary, if the owner of a shared file deletes it, you will no longer be able to access that file in your Google Drive.
