The Filr mobile app allows you to view most files within the app. Depending on the size and type of file, the app might need to be opened in a third-party app, or a warning might be displayed before you can view it in the Filr app.
The Filr app cannot display files of the following type that are larger than 20 MB on iOS devices and 2 MB on Android devices:
Text files (such as .txt, .odt, .pdf, and so forth)
HTML files
To view these files, you need to open the file in a third-party app, as described in Editing or Viewing a File in an External Application.
Because viewing a file within Filr consumes data (when using a mobile service provider), a warning is shown if you attempt to view a file over 5 MB in size.
When connected to Wi-Fi, a warning is shown if you attempt to view a file over 50 MB in size on iOS devices, because the process can be time-consuming.
