   attachments-1.zip
   └─── data
         ├── attachments
         │         ├── ProjectKey1
         │         │         └── 10000
         │         │		├── IssueKey-1
         │         │		├── IssueKey-2
         │         │       	└── IssueKey-3
         │         ├── ProjectKey2
         │         └── ProjectKey3
         └── avatars
   attachments-2.zip
   └─── data
         └── attachments
                   ├── ProjectKey4
                   ├── ProjectKey5
                   └── ProjectKey6
   attachments-3.zip
   └─── data
         └── attachments
                   └── ProjectKey7
   

3. Zip the files separately
4. Import the files batch by batch
