To open a disk image locally in Disk Decipher the disk image needs to be transferred to Disk Decipher first. To transfer a disk image to Disk Decipher, open the app which has access to the disk image (like Mail, Browser, Dropbox, ...) and open the disk image. The app should show the "Open In" option menu listing Disk Decipher as target.
If Disk Decipher is not listed in the "Open In" option menu, please double check the file extension of the disk image. For TrueCrypt containers the extension .tc is required. For FreeOTFE volumes (supported from version 1.2) the extension .vol is required. For LUKS volumes (supported from version 1.7), also use the .vol extension to transfer the disk image to Disk Decipher. For VeraCrypt containers (supported from version 2.2.0) the extension .hc is required. For Apple Disk Image (supported from version 3.3.0) the extension .dmg is required.
Starting with version 1.3 of Disk Decipher, you can also transfer disk images using iTunes (version 9.1 or later). This is especially useful to transfer large disk images. Instructions on how to use iTunes to transfer files are available on Apple Support.
Version 2.5.5 of Disk Decipher introduces the Import Local Disk feature. Using this feature you can import a disk image from other apps supporting document providing, i.e. apps whose documents are available in the Files app. This will copy the disk image from the providing app into the Disk Decipher app.
Finally, version 2.6 added Linked Disk support, which allows you to open an encrypted container provided by another app without copying it to Disk Decipher.
iOS 13 supports external storage. My "SanDisk iXpand" seems not to work however. How can I solve this?¶
The SanDisk iXpand will not work in the lightening port without the use of the SanDisk app.
Currently the SanDisk app errors out when you click on a file it does not recognise and gives you the option to “open with”. Instead of giving you a list of apps to choose from, the screen flickers and the option box disappears.
It works very well if you use the USB end of the device plugged into a USB to lightning adapter. This setup does not require the SanDisk app.
