你需要考虑一些约定。对于例如添加带有日期时间戳的前缀/后缀，上传文件的用户的名称等。



请查看以下链接，了解如何执行此操作：

You need to consider some kind of convention. For e.g. add a prefix/suffix with a datetime stamp, the name of the user who uploaded the file etc.

Look at the link below on how to do that:

与其他任何系统相同的方式：

1）附加版本号在文件扩展名之前（如果它是同一个用户）

2）将其存储在不同的文件夹中（如果它是不同的用户），这样用户只能看到自己的文件。

3）使用临时文件名存储它，并使用数据库将临时名称与真实名称交叉关联。



我使用GUID值作为存储文件名的第一个和最后一个方法以及使用GUID作为行索引的简单SQL表。

The same way you would do it for any other system:
1) Attach a version number before the file extension (if it's the same user)
2) Store it in a different folder (if it's a different user) so users only see their own files.
3) Store it using a temporary file name, and use a database to cross-correlate the temporary name to the "real" name.

I use both the first and last methods with GUID values as the stored file name and a simple SQL Table using the GUID as the row index.
