Extract text from FDMDOWNLOAD files
To convert your FDMDOWNLOAD file to another format, you need Free Download Manager or other Web software.
To convert other file formats to the "Partial Download" file type, you need software like Free Download Manager or a similar tool.
A .fdmdownload file is a temporary, incomplete data container created by Free Download Manager (FDM). It acts as a placeholder for a file currently being downloaded from the internet. When you initiate a download, FDM appends this extension to the original filename (e.g., installer.zip becomes installer.zip.fdmdownload) to lock the file and store downloaded chunks until the process creates a complete binary.
The catch for users is that .fdmdownload files are technically "broken" or truncated data streams. You cannot open them with standard software because the file structure (headers/footers) may be missing or incomplete. Users often encounter these files when a download crashes, the internet connection fails, or the source server blocks the connection, leaving them with a large, unusable file taking up disk space. Since the file format is proprietary to the download manager's logic, standard converters usually fail because there is no valid "source" format to parse.
To "convert" or recover these files, the most effective method is usually renaming the file to remove the .fdmdownload suffix. For example, if the underlying file is a video (like MKV or MP4), renaming it allows robust media players like VLC Media Player to attempt playback of the partial stream. For compressed archives like ZIP or RAR, tools like WinRAR or 7-Zip can sometimes extract whatever data was successfully downloaded before the interruption. If the download cannot be resumed in FDM, this manual "conversion" via renaming is your best option for data recovery.
Convert.Guru analyzes your FDMDOWNLOAD file, detects the exact format, and lets you read the text inside.
Users also converted FDM, TORRENT, NCA, NSP, MKV, MP3, CRDOWNLOAD, TXT, PNG, BAK, INP, AAE and PDF files.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our FDMDOWNLOAD converter.
