Failure in handling long path on network share.

[lcerman]

There is a problem with long path on network share. It seems universal. I observe it with WSL path or network drive mapped from a Linux host to a letter:

The internal viewer does not open (Cannot finish operation because of too long name), right clicking and selecting "Edit in Notepad" works just fine:

T:\home\lcerman\presser_foot_identification\data\results\bernina_vs_eccam,78classes,grouped22A22529C,tune,crop_size=352x260,lr=0.01,gama,mirrored,fro=True,efficientnet-lite-b2,ft=True,bs=32,pooling=average,decay=1e-05,do=0.1,epochs=20,2024-03-02T20-25-17\stdout

I have a folder in the WSL container with several images like this:
\\wsl.localhost\Ubuntu-22.04\home\lukas\presser_foot_syntetic_images\output\384x384\45434301_syntetic_eevee_static\pf_images_45434301_4_2024_03_02_20_11_43\im_prsm=Metal10,prsx=0.000,prh=128,fabm=Fabric7,fabr=0,fabmx=0.185,fabmy=0.029,lf=0.024,lb=0.023,lsa=73,lsp=40,camrz=0.000,ft=-4.png

The image thumbnails are not rendered, the internal viewer does not open the image (Cannot finish operation because of too long). Opening the same folder in Windows Expolorer works just fine. It shows the thumbnails and I could view the images in the default windows image viewer.

My setup:
Windows 11 Pro, Version 10.0.22631 Build 22631
Altap Salamander 4.0
reg:\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem\LongPathsEnabled is set to 1.

Looks like a MAX_PATH related issue: the first path is 261 characters, I have some other directories little bit shorter and these are OK.

It does not seem to be related only to network shares (but I guess that MAX_PATH applies also in case of a "standard" path with a drive letter at the beginning).
