Yeah, you can. I didn't know of its existence at the time, though. :P

Celtic can also ungroup files. But I'm not sure if it can ungroup corrupted group files

I have a question:
Sometimes, if I re-download and ungroup my backed-up file, some prgm says it only has 16 bytes of mem and if I try to run it, it ERRs me.
Is that the corrupted group file, or is it some thing else?
If it happens, how do I fix it?

Probably a corrupted group. It happens pretty often.

Like once in every 16384 groupings, but a lot of us have experienced it because of how often we use it :P

You can't fix that bug, unfortunately, but thepenguin77's released several OS patches for various group bugs. Look around :)

And so you should probably group each set twice just to be more secure.

That also happens when transfering a group file to your computer with TI-Graph Link or an old version of TiLP and TI-Connect, then send it back to the calc or WabbitEmu with more recent softwares/versions.

Groups aren't 100% reliable so I would be careful with them.

Just a random question: What are groups?

I've never needed to use them, so I have no idea what they are.

Lucky. I've probably experienced every group bug out there x.x

Qwerty.55, they're basically like ZIP files without the compression. You can copy any vars you want to a group, often for backup purposes. You can't edit the group directly, but you can ungroup them (kinda like "unzipping").

Btw, it's 2nd+[MEM] > 8:Groups...

yeah the cool thing about groups is that they can be ungrouped many times over so it saves the programs and pics and such and keeps them relatively safe :D

But as you can see by this thread (and all those posts where people lost all their progress by a corrupted group :P), you really shouldn't trust groups for all your backup purposes. Groups occasionally get corrupted, so you should backup on other calcs/comps periodically.

And you should use the patches made by thepenguin77 (they're posted in Other calculator discussion and news > ERR: VERSION). I can't put the link here because I'm in a proxy right now :P

EDIT: And yeongJIN_COOL, archive everything before you try deleting that 16-byte program. I've had that happen before, and when I tried to delete it, it reset my RAM.

EDIT2: Here they were: http://ourl.ca/6542.

My only issues with groups so far were when sending them to the comp with TI-Graph Link. They were stored in a different format not supported by newer versions of TI-Connect then all other software/emulators decided to keep compatibility with TI-Connect, meaning old groups corrupts when sent to them. Also when grouping stuff sometimes a byte is changed in the group file. So in a BASIC game you may end up with a nice ERR:SYNTAX in one of your program.

Oh, yeah, and TI sometimes doesn't even support their own group files. TI-Connect for Mac exports groups in .8xo form, but the group creator makes groups in .8xg format. Then you switch to the Windows TI-Connect, which doesn't even support the .8xo form.

Yeah and even if you rename them to 8xg they still won't work. X.x

I found DropBox very useful to backup online your project.
You have 2GB free and you can get more after following some tasks and inviting people.
This a tip more assembly or C calculator related, web development and other things. But you can also send from your calculator to computer and them put into DropBox.

For TI-BASIC you can also use SourceCoder2 in cemetech.
