Bug - openSUSE and USB keys I found that in copying from USB key to openSUSE, some file names got converted to lower case. This meant that scripts now broke. This is very BAD. Bizarrely, some were converted to lower case but not all. I can replicate the following behaviour. See if you can replicate this and let me know. I took files with names in all uppercase like DSCF0323.JPG and copied them in Windows onto a FAT32 USB key. When opened on openSUSE this is read as "Filesystem type: msdos" and the filenames are changed to lower case: dscf0323.jpg The following filenames however are not altered: DSCF0323.crop.JPG unchanged (remains mixed case) DSCF0323.lores.jpg unchanged (remains mixed case) file.jpg unchanged
