What Is a DDOC File?
A file with the DDOC file extension is a DigiDoc digital signature file that stores encrypted data. .DDOC is the file extension used in the first generation DigiDoc format, while the latest version uses .BDOC and stands for a Binary Document file. Encrypted DigiDoc files use the .CDOC suffix instead. These DigiDoc formats were developed by RIA. You can read more about the file format used with DigiDoc on their DigiDoc File Formats page. If not a DigiDoc file, your particular DDOC file may be a Digital Mars C, C++, or D macro file. Another possible format may be a graphic file used with Apple’s now-discontinued MacDraw software.
How to Open a DDOC File
DigiDoc4 Client should be able to open DDOC files on Windows, Linux, and macOS. There’s also the DigiDoc iOS app and DigiDoc for Android. This software is also used to authenticate government-issued ID cards, so it can both check that a document is signed and save documents (like Excel, Word, or PDF files) in this encrypted signature format. Depending on the version you’re using, you may see this alert when you try opening the file: We’re not entirely sure how DDOC files work with them, but if yours isn’t a DigiDoc file, then it’s probably associated with Digital Mars compilers. MacDraw was a vector drawing application released with Mac computers in 1984. It evolved into MacDraw Pro and then ClarisDraw in 1993, but isn’t available for download or purchase anymore. It’s probably highly unlikely that your file has anything to do with MacDraw. Your specific file could be saved in a format that has nothing to do with any of the formats already mentioned here, in which case a totally different program is required to open it. If you think this may be true, try opening it with a free text editor to see if there’s any identifiable text that can help you understand what program was used to create the file. You can then use that information to research a DDOC viewer or editor.
How to Convert a DDOC File
A free file converter is normally the way to go for converting one file format to another, but it’s unclear if there are any converter tools that support these DDOC formats. The only other way to convert a file is to use the software that opens it, via its save or export option. This might be possible with DDOC files that are used with Digital Mars software, but we don’t imagine that’s also true for DigiDoc files.
Still Can’t Open Your File?
Like you read in the note at the top of this page, some file formats use file extensions that look like they could be related to each other, like DOC and DDOC. This is usually a misunderstanding of the formats, which can lead to trouble when you try opening them. For example, DOC files open in word processor programs and can’t be used with DigiDoc or any other DDOC compatible software. The same is true the other way around, where DDOC files aren’t compatible with Microsoft Word programs or other text editors. This concept can be applied to other file extensions and their related formats, like DCD files, which could be DesignCAD drawing files or DisCryptor encrypted databases. DivX descriptor files that use the DDC and DDCX file extension is another example. If you don’t really have a DDOC file, research the file’s real file extension to see which program you need to view, edit, or convert it.
