I am attempting to carry out an extensive search for all Image files, which are mostly - but not exclusively .JPG files.
I have been attempting to do this using the 'Simple Find' dialog in Directory Opus, leaving all fields blank except 'Type', and I have been testing the search by initially searching a single folder containing some .JPG files. I am having difficulty in achieving a search for all image files that will return the .JPG files known to be present in the test folder.
Specifically, I can find no correlation bewteen the list of file types in the 'Type' drop-down list in the 'Find' dialog panel and the list of 'File Types' and 'File Groups' in Settings > File Types. And I can see no way of manually entering a file type in the 'Type' entry field. (I have also tried using the 'Advanced Find' dialog, but that still leads to the same problem with the 'Type' drop-down list.)
For example, the 'Type' drop-down list in the 'Find' dialogue includes an entry 'Image Files' - but that name is not listed in the Settings dialog for 'File Types', so I cannot ascertain what file extensions are included within that group 'Image Files' - but any search for "Type=Image Files" is completely negative.
Conversely, the Settings dialog for 'File Types' includes a File Group named "Images' - note the difference in name - (defined as including a list of about 17 file types) - but that group in NOT listed in the 'Type' drop-down list in the 'Find' dialog.
Incidentally, ".JPG" is listed solely as a "Photo Album 6 Photo", but searching for that will obviously not find other types of image files.
On a related issue, when using the 'Simple Find' dialog to search soley by File Type, it was not clear to me whether I needed to put a wildcard 'star' or 'star dot star' in the 'Name matching' field, or whether I could leave it blank. Both seem to work, but some guidance may be helpful.
I'm also slightly confused by the "Use wildcards" checkbox, because I would have expected that (a) the use of a standard wildcard character in the Name/Description field would automatically indicate that wildcards are being used and that the seacrh should understand that; and (b) in the absence of wildcard character being used in the Name/Description field, checking the "Use wildcards" checkbox would achieve nothing as there would be no indication as to where (and what type of) wildcard is permitted. Please clarify.
Finally, I cannot understand - not find any explanation of - the 'source / destination / new tab' dropdown at the right-hand end of the 'Find' dialog.
Thanks in advance for your help.
