[quote userid="294115" url="~/discussions/f/general/39264/document-upload-default-validation-message/148863"]a java smart service or function that returns file size[/quote]

not sure what this would do. if we're gonna require the user to do something, then it would be just as easy for them to read the file size themselves from whatever computer / device they're uploading it from.

Maybe creating a java smart service or function that returns file size and use it before uploading the file?

Before file upload you can’t check file size. Use helperText to warn users in advance.

How would a system validate a file before it's uploaded?

You can mofify the file size that can be uploaded, but not the message itself.

On Prem environment:
The validation message text cannot be directly modified because it is part of Appian's core validation system. The 30MB limit and its corresponding validation message are hardcoded into the platform's file upload components.
To adjust the maximum file upload size, you can modify the following system property:
In Configuring System Properties([APPIAN_HOME]/server/conf/server.properties) -> appian.upload.max.size -> Change to whatever you want.

I would recommend -> Use a document check rule before processing
