Description

File size is not a well defined concept for special Drive documents (Docs, Sheets, Slides) because it depends on the export format. For such documents, GCSF should report the corresponding file size they would have when exported with the default MIME type.

One way of achieving this is by exporting each document at mount time in order to obtain its real size. This is incredibly slow. For the moment, GCSF reports the maximum file size (10 MB) for all special documents.

Research direction
Examine how file sizes are currently reported in the GCSF codebase, particularly in the FUSE layer. Look into the Google Drive API documentation to see if there is a way to retrieve the exported file size without actually exporting (e.g., via the files.get method with fields=size). If not, consider caching exported sizes or exporting on demand. The issue has no comments or linked PRs, so no additional context.
