To quote the inimitable Klortho the Magnificent:

THE ERROR MESSAGE! READ THE ERROR MESSAGE!

The filename includes colons and that's not gonna work on Windows. It's not a problem with the directory, it's that $y includes invalid chars for Windows. C'mon, it's right in front of you.

As much as I hate to rain on your parade, it appears* to only contains one colon, and that looks like it's specifying a drive path. Surely this should work in perl?

* I say appears because I don't see where $y is defined, and it may contain a colon. But I can't tell.

change that to:  $zip->extractMember($y,"Y:\\autoupload\\Site_Dict\\Inbox\\$y"); and it should work like a champ, assuming that $y has been basename()'d.

From the perldoc:

extractMember( $memberOrName [, $extractedName ] )
     Extract the given member, or match its name and extract it. Retur
+ns
     undef if member doesn't exist in this Zip. If optional second arg
+ is
     given, use it as the name of the extracted member. Otherwise, the
     internal filename of the member is used as the name of the extrac
+ted
     file or directory. If you pass $extractedName, it should be in th
+e
     local file system's format. All necessary directories will be
     created. Returns "AZ_OK" on success.

Please note If you pass $extractedName, it should be in the local file system's format. All necessary directories will be created.
