Some days ago have been revealed some informations about the limitations introduced in latest Android 4.4 "Kitkat" version with external SD/MicroSD devices. This limitation consist in the impossibility for non-system apps (such as our Total Video Converter or MP3 Video Converter and other third part applications) to write or create new files in these external storage supports, despite reading permissions are still available. This decision, by the Android development team, derives from some security issues with the filesystem used by most of the MicroSDs, the FAT/FAT32. For this reason, TVC and MVC users will be able to encounter some "Permission denied" problems while writing to external MicroSD storages and this isn't in any way or form a problem of these two applications, so we will not accept bad or low star reviews for this issue. More informations about "Kitkat" external MicroSD storages writing permissions issue can be found here.
