Frequently Asked Questions from Customers

File conversion software is an application that reads a file in its original format, analyses its internal structure, and rewrites the content in a different format, preserving all elements: data, metadata, hierarchy, relationships and properties of individual objects. Depending on the type of file involved, the process may cover entire email inboxes containing thousands of messages, corporate databases with tables, queries and relationships, or individual documents in proprietary formats.

The typical workflow involves selecting the source file, scanning and analysing the internal structure with a preview of the convertible elements, choosing the target format or platform, and starting the conversion. The most comprehensive software allows you to filter content by date, sender or item type, to choose between multiple output formats in a single operation, and to perform batch conversion on multiple files simultaneously.

Microsoft and Apple’s native tools, Outlook’s import/export function, macOS Backup, and the Exchange Export Wizard handle the simplest cases within the same ecosystem, but have specific structural limitations in all cross-platform or cross-format scenarios.

Actual capabilities vary from product to product and edition to edition: before purchasing, it is always advisable to check that the chosen software supports exactly the source and destination formats required for your scenario. Mr Key Shop’s free technical support in Italian is available to help you identify the most suitable solution.

Choosing the right tool depends on four main factors. The first is the source format: the file to be converted may be an OST, an OLM, an EDB, an MDF, an MDB or an ACCDB; each format requires a specific tool that understands the internal structure of that file type. The second is the target format or platform: PST for Outlook, Office 365 for cloud migration, PDF for document archiving, or a database in a different engine. The third is the volume: basic tools cover a limited number of mailboxes or files, whilst advanced editions handle unlimited batch conversions. The fourth is the presence of advanced features such as direct export to the cloud, filtering of items to be converted, automatic splitting of large PST files, or recovery of items deleted during conversion.

In this category, ‘file conversion’ refers to the transformation of structured data files, email inboxes, databases and document archives from one proprietary format to another, whilst preserving the internal structure, metadata and all elements of the original file. This does not involve the conversion of images or videos, but rather the migration of data between incompatible platforms and formats.

Repair software works on corrupted or damaged files that can no longer be opened, reconstructing their internal structure to make them accessible again. Conversion software works on files that are intact but incompatible with the target platform, converting their format to make them readable by a different application or system. Some tools combine both functions.

Yes. All professional conversion software preserves the folder hierarchy, subfolder structure and item metadata—including date, sender, recipient, subject and attachments—exactly as in the source file. A flattened structure or loss of metadata are typical problems associated with manual conversions or native tools.

No. Professional conversion software works in a non-destructive manner: it reads the source file without altering it and creates a new file in the target format in a separate location. The original file always remains intact.

CAD (Computer-Aided Design) software is a tool for creating, editing and documenting technical drawings and 3D models with mathematical precision. It is used by architects, engineers, mechanical designers, industrial designers and technicians across all sectors to produce design drawings, three-dimensional models and professional technical documentation.
