Major - P3 Description
The colon character is reserved in NTFS and cannot be used in a filename. MongoDB encounters irregular and strange errors in various situations involving colons in collection names, which allow colons.
We recently had a dump of a database with collection names like "500:backfill:2047". That dump won't copy to a Windows volume.
Attempting to dump a database with collections containing a single colon will create corrupted dumps with the colon indicating an alternate data stream:

Add another colon to the collection name will cause mongodump to crash.

Mongodump should dump to a file format that's compatible with Windows.
