With the MAS version, I get the following warning if I double-click the file:
If I drag it to iLocalize, I get:
and the Console reports:
13/10/13 5:37:13.290 PM iLocalize[14944]: [ERROR] class=ApplicationDelegate, method=-[ApplicationDelegate openLastOpenedDocuments], message=Unable to open recent document /Volumes/VifArgent/Users/corentin/Desktop/Localizable.xliff: Error Domain=NSCocoaErrorDomain Code=256 "“Localizable.xliff” could not be handled because iLocalize cannot open files in the “Document” format." UserInfo=0x786030 {NSLocalizedFailureReason=iLocalize cannot open files in the “Document” format., NSLocalizedDescription=“Localizable.xliff” could not be handled because iLocalize cannot open files in the “Document” format.}
If I remove one f from the extension, then the file opens up just fine.
