If you see an error stating you don’t have read/write permissions during a compression session, please make sure that you have the read and write access on the external hard drive you want to use with Rawsie:
Using Rawsie with NTFS drives
We suggest using ExFAT formatting over NTFS formatting, because NTFS is not natively supported by MacOS. However, if you still need to use Rawsie with an NTFS-formatted drive, you need to make sure that Rawsie has the read/write rights on this drive. To test if the system has the rights – try to copy a file from your machine and paste it onto the disk in question.
