" \ "\r Because it's a port !! Unlike MacOS: As far as I know all other "\ "\r Operatingsystems (eg.: Unix, DOS, OS/2, ...) are based on pathnames" \ "\r " \ /* a short quote from "Inside Macintintosh, Files"; slightly modified by me */ "\r On a Mac: Files and directories located in the same directory " \ "\r must all have unique names. However, there is no requirement " \ "\r that volumes have unique names. It is perfectly acceptable for two mounted" \ "\r volumes to have the same name. This is one reason why a application should " \ "\r use volume reference numbers rather than volume names to specify volumes," \ "\r but for this Zip-Port I can't use reference numbers. " \ "\r " \ /* end quote */ "\r" \ "\r From the developers point of view:"\ "\r The use of pathnames, however, is highly discouraged. If the user changes"\ "\r names or moves things around, they are worthless." \ "\r Full pathnames are particularly unreliable as a means of identifying files," \ "\r directories or volumes within your application," \ "\r for two primary reasons:" \ "\r" \ "\r* The user can change the name of any element in the path at" \ "\r virtually any time." \ "\r* Volume names on the Macintosh are *not* unique. Multiple" \ "\r mounted volumes can have the same name. For this reason, the use of" \ "\r a full pathname to identify a specific volume may not produce the" \ "\r results you expect. If more than one volume has the same name and" \ "\r a full pathname is used, the File Manager currently uses the first" \ "\r mounted volume it finds with a matching name in the volume queue." \ "\r" \ "\r" \ "\r The main reason is that an attempt to implement support exact saving of" \ "\r the MacOS specific internal file-structures would require a throughout" \ "\r rewrite of major parts of shared code, probably sacrifying compatibility" \ "\r with other systems." \ "\r I have no solution at the moment. The port will just warn you if you try" \ "\r zip from / to a volume which has a duplicate name." \ "\r MacZip has problems to find the archives and files." \ "\r" \ "\r" \ "\r ... and the moral of this story:" \ "\r" \ "\r Don't mount multiple volumes with the same " \ "\r name while zip/unzip is running" \ "\r and "\ "\r My (Big) recommendation: Name all your volumes with a unique name "\ "\r (e.g: add a space character to the name) and" \ "\r MacZip will run without any problem." \ "\r" \ "\r" \ "\r Dirk Haase" \ };
