 This script will convert your HEIC files (a format Apple saves photos with) to JPGs. Flip saveasjpg at the top to save as PNG instead. This will result in much larger file sizes. Set keeporiginals to 0 to delete the HEIC files after they're converted. The HEIC files are saved kept around by default. For best results set this up as a cron job.  
 \* Requires the ImageMagick CLI software to be installed with HEIC support. There are links at the top of the script to do this.
 
+**convertFLACtoALAC.sh**  
+This script converts files from the FLAC format to the ALAC format (Apple's lossless codec). For some reason iOS doesn't natively support FLAC in the default music app so this is my way to make it work.

 **cleanupBeatSaberSongs.sh**  
 I wrote this script because I was tired of using the excuse that the folder names are jibberish (98e299036de1688c3f60cda87728ee3c2969188<wbr>8 for example) to not clean up my custom song library. This script goes through all the folders that are 40 characters long (didn't check for only hexadecimal characters so be warned ye ol 40 character song titles), extracts information from their info.dat files (in 2 ways funny enough), and renames the folders to the actual song names with the artist and mapper separated by hyphens. This way if you happen to have a song mapped by different people they don't get overwritten.
