corrupt file

[j.nguyen]

Just opened my file this morning to back it up on my server and got a corrupt file error. No, I am not trying to go back a version. Currently using X4 13.0.3.31.

 

The message is " Corrupt or invalid file. Contact you local Mastercam Dealer "

 

Then.....

 

"Parasolid® Kernel Inerface Error: 922-

invalid file contents"

 

Anyone have any insight on this one other then save a back up? I am going to turn on Autosave.

Turn on autosave as this file is toast. Sorry to say.

May be check your config file and check your autosave file path . May be auto save is happenning and you may be unaware.

Have a look.

I would highly recommend using "backup files" instead of "auto-save". The "backup files" feature can save incremental backups of a file every time you save it and keeps them in the location of your choosing. Using auto-save would leave you vulnerable to the exact same problems if a file is ever corrupted.

[gcode]

make sure the filetype dropdown is set at MCX

I've had this alarm before when the filetype dropdown did not match the type of file I was trying to open.

and..

Turn your backup utility ON!!!!

 

There is a really useful backup utility

at

Settings/Configuration/Files/AutoSave/Backup.

I have it set to 10 saves (on my C drive)

I leave 3 months worth on a C drive and delete

a months worth at the end of every month..

Not only will it save you from crashes

and this corrupt file issue,

It can save you from brain farts and operator errors.

If you do something dumb that will cost you a

lot of time to correct, just go to your backup folder and open the last save before your brain fart.

 

This utility is a life saver and there is absolutley no penalty for turning it on.

You'll never even know it is running... untill

you need it.

Personally I hate the autosave function. I much prefer the "Backup" utility instead. This will save an incremented copy of your file to your backup directory. This allows you to have a running backup of the last 10 saves you've done to your file (you can set the number of saves to what ever you want, the default is 10).

 

I've seen it happen quite often where the last 3 or 4 backup copies in the directory are toast, but there is at least one that is recoverable, and can save your bacon.

 

Here is the really important thing to note: Even if you have Autosave turned on, if your file becomes corrupt, Autosave will still work and automatically save your now corrupted file.

 

Bummer.

 

That is why I think the Backup utility is a much better option...

[gcode]

Back in my V9 days I was doing really large

5axis files. A Save would take 30 to 90 seconds..

I'd been clicking away and autosave would be trying to save a moving target, cause I'm still working.

The end result would be crash and (2) 0 byte files

 

I quit using Autosave and havn't used it since..

The backup utility is far superior..

I really can't think of any reason not to use it.

It has saved me more times than I can count.

I have not had a corupt file since the 'dimension

crash', I believe in X2. I only do one back up and

have had good luck even with all my other woes.

 

If auto saves can corrupt a file, I might suggest

CNC remove it from the software???

[Colin Gilchrist]

Rickster,

 

Autosave works great for programmers that work on small files. Some people like it, but I'm with Gcode, I only use the Backup function...

 

I would like to see Autosave turned off as a default, but I don't think that is going to happen. I'm content to just turn it off myself...

It seems though CNC needs to work on thier

'large file issues' as a priority.

I just installed a 2nd hard drive in my laptop and had my back-up files point to it. I guess everything happens in 3's ....Hard drive crashes lose work, corrupt file lose 4 days, so this is the 3rd time i get to program this parts. Isn't it funny that these things only happen when you are pressed for time and you let your guard down?

 

Thanks for the advise I will be backing up on a regular basis.
