No matter how much disk capacity, it will be filled up very soon. One of main reasons is there are always too many junk files, including the big and repeated ones. To effectively release the disk space, in addition to using some disk cleaning or duplicate file finding tools, another effective means is to find and delete some big and useless files! However, to manually locate those large files by checking the size of files/folders is distinctly not practical, so we need to utilize some edge tools to automate and visualize this process.

As is known to all, software used for 3D modeling can be found everywhere at present. However, they almost always use their own exclusive file formats, which are incompatible with each other. In order to realize data sharing and exchanging between these 3D software, sometimes, we have to convert the 3D model files generated by different 3D modeling software to our desired formats. This case, a 3D file converter that supports batch processing is necessary.

MKV (Matroska Multimedia Container) is an increasingly popular video format. In some cases we need to extract the resources from MKV video so as to obtain the video, audio and subtitles inside separately for other use. For example, make an audio version of a film/TV play; edit, modify, or translate the subtitles (and then use MKVToolNix to repack them all). At this time, we can use MKVExtractGUI this tiny app to solve the requirement perfectly.
