Just for clarification - is the FAT32 drive created by BoxCryptor genuinely FAT32. I have been unable to test this on the free version & would like to know if I am able to store files greater than 4Gb there if I to unlimited.
No, the BoxCryptor drive is no real FAT32 drive. You should be able to store any file size in the BoxCryptor drive which is supported by the file system where the encrypted folder is located, e.g. > 4GB on NTFS volumes.
