Imports compared
What matters most on a phone or tablet is whether the study you received actually opens. Ossidex handles these sources:
| What you have | How it gets into Ossidex |
|---|---|
| Disc folder with DICOMDIR | Import the whole folder; the Windows viewer (.exe) next to it is skipped. If you pick the .exe by mistake, Ossidex suggests importing the folder instead. |
| ZIP / RAR / 7z / ISO | Imported as is, archives inside archives unpacked; password asked only for encrypted archives. |
| Cloud share link | Google Drive files and folders, Dropbox, OneDrive and SharePoint, iCloud Drive shared files, WeTransfer, Yandex Disk, Mail.ru Cloud, direct URLs. Interrupted downloads resume. |
| Loose .dcm files | Grouped into studies and series; files without UIDs or without the DICOM preamble are recovered where the data allows. |
| PACS | DICOMweb search (QIDO-RS) and download (WADO-RS). |
IMAIOS does not publish an equivalent list; check its documentation for your case.
Who should pick which

Which one should you use?
