Face ID ?

Sorry. Face ID gefunden.

Schön wäre, wenn man die VeraCrypt Container mit Face ID öffnen könnte.
FTPS wäre ein weiterer Wunsch.
Sonst alles perfekt.

Response from developer

Thanks for the FTPS suggestion, I've opened a feature request for that on https://gitlab.com/huv/disk-decipher/-/work_items/437 to allow others to vote/comment on it. Let's see if there is more interest in FTPS.

Avoid

If I could leave negative I would, it expects you to pay an extra £2.99 for exFAT file system support or £6.99 for all file systems . Considering you already pay £0.99 for the app in the first place!

Response from developer

Both the App Store description and the support site (https://disk-decipher.app/filesystems/) explain that the extra purchase is needed to cover 3rd party licensing and royalties costs.

Läuft Super auf IPad Pro M4

Vielen Dank für dieses super Programm. Es kann problemlos die Inhalte meiner „alten“ TrueCrypt-Container auf IPad Pro anzeigen. Eine Spende schicke ich später noch an den Entwickler!
Einen Wunsch hätte ich noch für ein Update: In meinem Container liegen viele Bilder und der Rahmen der Thumbnails ist sehr Groß bzw. Dick! Wäre es möglich diesen viel kleiner/dünner zu machen bzw. eine Option die Dateinamen auszublenden!

Problème pour l’écriture.

Bonjour. Merci pour votre application.
Je signale un problème. Les disques locaux sur iPad fonctionnent parfaitement. Mes disques sur cloud : PCloud et Dropbox, ne permettent plus l’écriture depuis pas mal de temps. Pouvez-vous faire quelque chose ?
AAdrien72100

Response from developer

More info on write support is available here: https://disk-decipher.app/write-support/#storage-provider Dropbox (used as remote disk) never had write support, due to API limitations. pCloud used to have write support, but pCloud removed that capability from their API in 2025, more info on that here: https://disk-decipher.app/remote-storage/#pcloud You might want to install the Dropbox app and access your disk as Linked Disk, as described in this example: https://disk-decipher.app/disk-types/#example That will allow write access.
