Understanding OSC Issues
Typical OSC Opening Challenges
Merkaartor Removed
You encounter an error message such as "%%os%% Can't Open OSC Files" when trying to open your OSC. When this happens, it is commonly due to Merkaartor missing in %%os%%. Your operating system cannot associate your OSC with Merkaartor, so double-clicking the file won't work.
Tip: If you know of another program that can open your OSC file, you can try opening it by selecting the application from the programs listed.
Obsolete Version of Merkaartor
Sometimes your installed version of Merkaartor won't support your OpenStreetMap Change File file. If you do not have the proper version Merkaartor (or any of the other programs listed above), you may need to try downloading a different version of it, or one of the other software applications listed above. Most of the time your OpenStreetMap Change File file was created by a newer Merkaartor than what you have installed.
Tip: Investigate your OSC file by right-clicking and selecting "Properties" to find clues on what version you need.
Primarily, problems experienced when opening OSC files are due to having the incorrect version of Merkaartor installed on your computer.
Other Causes of OSC File Opening Problems
Errors opening OpenStreetMap Change File files can still occur even with the latest Merkaartor software installed on your computer. If you are still having problems opening OSC files, there may be other issues that are preventing you from opening these files. Problems unrelated to software:
- Windows Registry OSC file paths that are incorrect
- The OSC file description within the Windows Registry was removed
- Corrupt install of Merkaartor or other OSC-related program
- The OSC itself is corrupted
- Malware-tainted OSC file can't be opened
- OSC-related hardware has device drivers that obsolete
- Insufficient system resources to successfully open OpenStreetMap Change File files
