How to force PyCharm to use the file in drive instead of the file in its local history?

Hi all,

I used Google Drive to synchronize files between multiple computers. But I found that when the changes are done in Computer A and synchronized to Computer B. PyCharm in Computer B won't read the updated file, instead, it will somehow use the last opened version in its memory.

So my question is how can I force PyCharm in Computer B to read the latest file in the drive instead of from its memory.

Recommendations/alternatives are welcomed but please I would also want a solution to the above-mentioned problem.

Thanks a lot!
