Hi, I have this application where I'm able to upload and download files that are stored in SQL. However, when I download a file, make changes and upload again I get a duplicate file stored in the database. I want to overwrite the existing file. What's the best approach to this feat?
Also, some files may be access databases. Normally, multiple people can share an access database and make changes simultaneously. Am I correct in assuming that I won't be able to keep an access database in sync if two people download at the same time and upload their changes?
Thanks in advance.
