Hi,

The "upload.max" setting is no longer valid in DSpace 7.  It was removed 
during the 6.x -> 7.x upgrade, as it only applied to DSpace 6.x and below.

Because DSpace 7 uses Spring Boot for the backend, you can use Spring 
Boot's own settings to tweak the maximum size of an uploaded file.  See
https://spring.io/guides/gs/uploading-files/#_tuning_file_upload_limits

By default, DSpace 7 sets both "spring.servlet.multipart.max-file-size" and 
 "spring.servlet.multipart.max-request-size" to 512MB in this file: 
https://github.com/DSpace/DSpace/blob/main/dspace-server-webapp/src/main/resources/application.properties#L127-L134

However, you can override those defaults by specifying a *new value* in 
your "local.cfg" (as any settings in local.cfg will override defaults in 
that application.properties file).

So, you could, for example set: "spring.servlet.multipart.max-file-size = 
1GB" to add a 1GB limit.  I believe you can also set these to "-1" to make 
the file upload unlimited (however there is always a risk that a very large 
upload will still fail if your request simply times out in Tomcat.)

Hopefully that helps. Let us know if there are other questions on this list.

Tim
