Describe the bug

When doing a backup to Dropbox, my nether and end worlds would usually upload just fine but when it gets to the overworld and plugins folder, it cannot upload successfully and return an error (java.lang.NegativeArraySizeException: -239833609). Can you please fix this since I would like to regularily upload backups as I am using Oracle Cloud Infrastructure free tier as my hosting provider which is rumored to delete entire servers at anytime for any reason whatsoever.

Additional Context

No response

I seem to have found the issue. The exception is occurring at line 200 of DropboxUploader.java meaning that the files are not getting split into chunks. Because Dropbox has problems uploading large files, this is causing the error. I tried doing a backup of a folder where the compressed zip equals 8 GiB, and it looks like it did not split the backup into chunks causing this exception. I have the Dropbox Plus plan which has 2 TB, so it's not a problem of available space.

It looks like it might have overflowed the value, causing it to be negative. Changing the variable type from int to long should fix the issue as file.length() returns a long value. Given that file.length() is returning the size in bytes, then a size bigger than 2,147,483,647 bytes (2.1 GB) would cause it to overflow.
