The NextZXOS can read and load these kind of files: bas, tap, nex, z80, sna, snx, dot, o, p

.z80, .sna and .snx are Spectrum snapshots, more suitable as emulator compatibility than a real format
.o is a ZX80 snapshot
.p is a ZX81 snapshot
.nex is good for a program that takes over the machine
.dot is good for dot commands and programs that can coexist with BASIC/NextZXOS and can return to BASIC safely (i.e. counterpart to nex)
.tap is a simple container format that can hold many files, is compatible with emulators and supported by many tools.
.bas is the native SD-card format for BASIC programs (first 128 bytes of the file form standard +3DOS header).
.scr is used for a standard Spectrum screenshot created with SAVE "picture.scr" SCREEN$ (256x192, 15 colours per character cell).
.shc is used for a screenshot in Timex 8x1 Hi-colour mode (256x192, 15 colors).
.shr is used for a screenshot in Timex Hi-res mode (512x192, mono).
.slr is used for a lo-res screenshot (128x96, 256 colours).
.sl2 is used for a Layer 2 screenshot (256x192, 256 colour).
.pal is is a 9 bit palette format (256 pairs of bytes in RRRGGGBB, P000000B format). Files can be loaded and saved from the Screenshots menu in NextZXOS after pressing the M1 button or F9.
