Prerequisites

  • Are you running the latest version?
  • Can you reproduce the problem in the debug version?

Check and fill as appropriate:

  • I was running Aaru under Windows 7...
  • ...in 64-bit

Description

When specifying an MDS image that resides in a different path, the corresponding MDF file is only searched in the current directory, not in the directory where the MDS file is

Exact command line used:

aaru filesystem ls "d:\Downloads\some image file.mds"

Expected behavior:

a listing of the files in the image

Actual behavior:

Image format identified by Alcohol 120% Media Descriptor Structure.
Unable to open image format
Error: Cannot open data file

Obviously, it works correctly if I cd to the corresponding directory first

Output of command execution with debug output enabled
