Can't send to compressed (zipped) folder

I'm IT Technician at a Secondary School and our Network Manager is away on long term leave. Currently our student's aren't able to send to - compressed folder. When trying the error 'File not found or no read permission' appears. It works for staff so I can only imagine it's a group policy setting. I have minimal knowledge on GPOs. My understanding is temp files are used on the C: drive when creating zip folders, and I've tried giving a test student full access to these but this didn't work. Third party (7-zip) also doesn't work.

Windows 7 with mix of 64/32 used. Server 2008 R2 Enterprise.

Any help massively appreciated!

I had files locked in the folder.

Once I closed the programs that had the file locked, I could create a zip file successfully.

Make sure that they have access to the temp folder (I know, you said you tried the C drive, but please double check); this error message usually means that zip fails because they don't. Also, the temp folder in question might not be c:\temp. Check in Computer Properties/System Information -> Advanced System Settings -> Advanced -> Environment variables. (Mine is %USERPROFILE%\AppData\Local\Temp.) The students need access to that temp folder.

Good luck!

I came across a very similar issue in Windows 10 regarding being able to zip a .sql file. The message I received was "file not found or no read permissions". I tried adjusting the security and permissions on the file and moving it to a different drive/folder but nothing changed. What I did notice, however, is that this particular file did not have a "date modified" value. So, I opened the file in Code Writer, added a space to the end of the file, and then saved it. This created a "date modified" value and thus I was able to zip the file. I suspect that some other application had a lock of some kind on the file.
