Then the absolute path of your space is "D:WEBABC", so, for example, you put the file in your space web directory, then the absolute path of the file is "D:webabcweb", in the case of you if you put the file in the Databases folder, then the absolute path of the file is "D:webabcdatabases"

This is the relative path, so try to avoid using the absolute path in the program to use the relative path, so that no file can be found after uploading to the server
