Attachments

A file you drag in is kept inside Tisty and named by a stamp of its bytes. It is written like a picture, with the label you see:

![Rina on her chair](rina-on-her-chair-3f9a1c2be8d47a60.jpg)

![Rina's vet card](vet-card-9d02e4b7c1f3a85e.pdf)

• A picture is drawn; any other file is a chip with its label that opens it.
• The stamp is 8 to 16 lowercase hexadecimal characters after the last dash, and the whole name is lowercase.
• Documents written by an older Tisty that say attachments/ab/name still read; when the document is rewritten, only the name is kept.
• When a document is written out to a folder, its attachments go beside it and the links point at them.
