If a user open to edit a document and another check it out. If the user that has the document open to edit make changes to the document. The individual that has the file check out looses his/her mark ups, why's that?
because checkout is a soft checkout/lock on the file it does not restrict anyone else from editing the file. anychanges made by one person will/can be lost. a true windows file server is the only way to combat that. you have to train people to look and see if someone has checkout the doc and even communicate because people always make mistakes
I always thought that having a file check out obstruct another person from making edit to that particular file, given that when a file is checked out you can only download a copy. My team and I recently noticed that if the file was already open to edit before it was check out. The person who check the file out may lose his/her markups which is very strange. Now, you said that we will have to train everyone to look and see if a file is checked out, we understand that. That isn't the case, like I said you may just be looking at a file (While no one has it check out) someone then check it out without you knowing and you accident made changes and that person looses hours of mark ups. That is a huge problem, and since discovering this we have been trying to find a solution. I think the check out feature would be a lot more effective if no one could make changes to that file regardless if it was open by another user before it was check out.
yes but you have to consider the various tools such as the Sync tool. what if the person is offline and cant see that the doc is checked out and makes changes while it is checkout. it does not matter where you go this is an issue with cloud storage don't think there are going to be many who have a solution because of how the architecture is designed.
just to be clear im not advocating for sharefile because they have there issues just like everybody else, but this i beleive is going to be an issue you experiencie across all cloud storage platforms. I have experienced the same using Sharepoint and others. let me know if you do find one because maybe i will jump ship.
