Delete Branch "%!s(<nil>)"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?

Short description of error
VSE seems to delete blend files after opening and sometimes after saving.
Exact steps for others to reproduce the error
After opening a VSE .blend file containing large (4 hr) video files the .blend file is removed from the working directory.
Sometimes these .blend files are also deleted sometime after saving
On save and exit from Blender via the File --> Exit the .blend file is missing and must be recovered on the next session start
All files are in the same directory Blender should have adequate permissions.
Errors reported:
On save:
Unable to make version backup
Version backup failed (file saved with @)

Thanks for the report, but I fear this can't be triaged as a complete bug report :
For the development team to be able to help, there needs to be reproducible steps (start blender, press this, then that ...).
Reports without steps for others to reproduce the error take a long time to be investigated, so priority is given to other reports.
After each save, blender create a backup file
.blend1
are you working on a backup file?Added subscriber: @iss
I think I can reproduce this with disk cache enabled if .blend file is located in same path as disk cache is.
@Magdes Click on Edit > Preferences, then in preferences window go to System tab and expand Video Sequencer panel
Check if Use Disk Cache is enabled
If it is enabled check if Directory is same as path to .blend file
Disk cache subdir has same name as .blend file, if there is no versioning file in that directory doesn't have versioning file cache will try to remove it with
BLI_delete(path, false, true)
.Attempt to delete file with this function fails on Windows, because it expects directory, I will check on Linux as well.
Disk cache directory is meant to be system wide directory dedicated only for cache, and it shouldn't contain .blend files. So not sure if this would be bug or not strictly speaking.
I would say that it definitely shouldn't delete .blend files though.

I do have Use Disk Cache enabled and it was pointing at another directory. I've changed it to point to the same directory as the blend files.
The problem manifests slightly differently now.
Updated steps to reproduce the issue with the directory change mentioned above:
Starting condition: blend file in the same directory as the disk cache, no other files in the directory at blender start
Launching by clicking on x008.blend@ in the file explorer does work, but now I'm in a loop that will append @ to my file extension after my second save attempt (x008.blend@@, x008.blend@@@ etc...)
Thanks again for your help @Germano Cavalcante (mano-wii) and @richard-27 Antalik (ISS)

@Magdes Thanks for information.
Turning file into folder is not very good either, and I will make fix for that.
Now I would like to check your original problem again, when disk cache directory was not same as path to .blend file.
Can you check if .blend file will get deleted if you disable disk cache?
I've tried a few different directories on different physical disks, but I am unable to reproduce the original behaviour. I am still seeing the .blend file to directory and blend file to blend file@ problems though.
I think this is problem unrelated to sequencer. I thought about disk cache, only because it uses .blend file name in it's path and it does delete files, but issue there is different.
Provide as much information as you can, that is provide .blend file you have problems with, go to directory of .blend file in console and run
pwd; echo test > test.txt; mv test.txt test.txt1; ls -al; rm test.txt1
and paste output here.Do you have this problem with all .blend files in all locations?
Do you have problems whe you create new .blend file? Or does Blender behave normally in some case?
Also check if this is regression in 2.91 - try checking older releases down to 2.79 from https://download.blender.org/release/
And check latest alpha as well https://builder.blender.org/download/

Is this issue still happening? Anyone managed to reproduce?
I wasn't able to reproduce issue as described, but there is issue when you can set disk cache path to
//
and it would turn .blend file into directory. I forgot to fix this issue. I should have made new report for that, so I won't forget as that is quite serious bug.Can you handle this now? :)

What is the status of this @iss?
Changed status from 'Needs Developer To Reproduce' to: 'Needs User Info'
Disk cache issue has been resolved, Looking through messages and original report ,I think that this could be cause of original issue (file saved with
@
due to folder with same name created). But also it has been said, that different cache directory was used when issue has been reported.@Magdes Can you download latest 2.93 or 3.0 build from https://builder.blender.org/download/daily/ and check if issue has been resolved?
If there are no issues anymore this could be closed and
5368859a66
could be considered as fix.Changed status from 'Needs User Info' to: 'Archived'
No activity for more than a week. As per the tracker policy we assume the issue is gone and can be closed.
Thanks again for the report. If the problem persists please open a new report.
